EXECUTIVE SUMMARY

California’s publicly owned utilities (POUs) have collaborated since 2006 on evaluating energy efficiency programs and reporting annual results in a consistent and comprehensive manner. This eleventh report explores the latest results from public power’s wide range of energy efficiency programs. During the 2016 reporting cycle, POUs spent over $154 million on programs, resulting in more than 825,000,000 kWh of gross annual energy savings. When added to the total investments since the signing of SB 1037, public power has spent over $1.37 billion on energy efficiency and achieved nearly 63.6 billion kWh in lifecycle energy savings. As a whole public power is becoming more efficient at energy efficiency. From 2014 to 2016, annual energy savings grew by 3.7%, while program costs declined by 11.3%. As the state looks to double the energy savings from energy efficiency by 2030, the ingenuity and collaborative spirit of public power will be even more critical. The continued success of the past year provides an excellent foundation on which public power looks to build upon.


INTRODUCTION

This report reflects public power’s response to a number of key pieces of legislation. Assembly Bill 1890 (Brulte, 1996), infamous for facilitating the Energy Crisis in 2001, also plays a prominent role in California’s energy efficiency legacy. The bill established the Public Goods Charge through which publicly owned utilities (POUs) have funded energy efficiency programs for over two decades. Senate Bill 1037 (Kehoe, 2005) required each POU to report annually to its customers and the Energy Commission on its energy efficiency and demand reduction programs. Assembly Bill 2021 (Levine, 2006) directed each POU to identify all potentially achievable cost-effective, reliable, and feasible electricity efficiency savings and establish 10-year energy efficiency targets. Assembly Bill 2227 (Bradford, 2012) changed the frequency of the 10-year energy efficiency potential studies from once every three years to once every four years to be consistent with the State’s Integrated Energy Planning process. Senate Bill 350 (De León, 2015) required the annual report to include a comparison of actual energy efficiency savings to the annual target adopted in the most recent 10-year potential study. The bill also directed POUs to develop energy efficiency targets consistent with the statewide energy efficiency targets adopted by the Energy Commission.

This report compiles the required data from individual POUs into a single, comprehensive document in compliance with §9505 of the Public Utilities Code. Furthermore, this compilation fosters analysis of broader energy efficiency trends and offers policymakers data-driven considerations regarding the practical impacts of their policies. The purpose of this report is not only to look back on the success of the past year, but also to look ahead and inform discussions on how to achieve additional energy savings in the future.

As California looks to double the energy savings from energy efficiency by 2030, it is critical that policies and programs aim to remove barriers for, and encourage voluntary action by, customers to reduce their energy usage to realize all cost-effective and feasible potential energy savings. Whether the state adopts codes and standards that are more stringent for existing building retrofits or a utility offers rebates for more efficient appliances, the customer is ultimately responsible for the decision to comply, manage, invest, or otherwise implement an energy efficiency measure. This guiding principle of energy efficiency – that the customer is key to savings – drives POU program design and implementation as a natural extension of public power’s broader mission of tailoring utility services to the specific needs of their unique community. Locally elected boards, such as a city council, govern POUs and are accountable to the customers they serve. While harnessing proven global innovations and, in many cases, helping advance emerging technologies, POUs are first and foremost responsive to local concerns regarding energy efficiency programs. California POUs serve a diverse range of customers and communities. Key characteristics include building climate zone, customer class, annual retail sales, and customer economic conditions. Based on these factors, POUs develop energy efficiency programs to

optimize benefits in and for their local communities. Bui lding Cl imate Zones Building climate zones are one of the primary factors driving energy efficiency program design. California is divided into 16 separate and distinct climate zones, defined by multiple factors, including summer temperature range, record temperature highs and lows, annual precipitation, and seasonal differences. POUs are located in 13 of the 16 climate zones, ranging from Truckee Donner PUD over the Sierra Crest to Merced Irrigation District in the heart of the Central Valley to downtown Los Angeles, the nation’s second largest city. Customer heating and cooling needs vary significantly among climate zones. As a result, the energy savings from HVAC retrofits differ dramatically across utilities and climate zones. For example, an HVAC retrofit in the City of Needles in Climate Zone 15 – characterized as extremely hot and dry – yields considerably greater energy savings than a similar HVAC retrofit in a coastal community like Lompoc (Climate Zone 5). The climatic conditions that make for a cost-effective energy efficiency investment in one POU community may not deliver the same energy benefits and cost savings for a similarly situated customer of another POU.

Customers are ultimately responsible for achieving savings from energy efficiency.


Customer Class Customer class (i.e., residential, commercial, industrial) distributions vary from utility to utility, and affects energy efficiency planning and program efforts. Residential customers consumed approximately one-third (33.9%) of all electricity delivered by California POUs in 2015. Traditional programs for residential customers are increasingly not cost-effective. State and federal standards have made modern appliances and HVAC units so efficient that the energy savings from ultra-efficient models compared to base models is much less significant than in previous years. To be clear, there remains a great deal of cost-effective energy efficiency potential in the residential sector. However, significant barriers, including customer access to financing, additional code requirements, and building owner interest, make deeper energy retrofits in the residential sector challenging. The report discusses these barriers further in the Po l i c y Con s i de ra t i o n s section. Non-residential customers consume more energy per account than residential customers do. In 2015, the average POU non-residential account consumed 115.1 megawatt hours; in comparison, the average POU residential customer consumed 7.2 megawatt hours.1 By virtue of their higher usage per account, non-residential customers present the greatest opportunity to achieve cost-effective energy savings.

1 Data from forms EIA-861 and EIA-861S. Available: http://www.eia.gov/electricity/

To deliver a cost-effective portfolio of energy efficiency programs, POUs balance their program offerings for non-residential customers and residential customers. This ensures the portfolio is cost-effective, even if individual programs are not. More importantly, it ensures all customers have access incentives for energy efficiency. Figure 2.

Annual Retai l Sales California is home to POUs of all shapes and sizes. Figure 3 below depicts POU retail sales grouped by size:

• LADWP & SMUD • IRP POUs: the 14 POUs, in addition to

LADWP & SMUD, subject to the Integrated Resource Plan (IRP) provisions of SB 350

• Non-IRP POUs: 23 smallest POUs not subject to the IRP requirements

Figure 3. Retail Sales (MWh), 2015

Source: U.S. EIA and California Energy Commission

At the larger end of the spectrum, Los Angeles Department of Water and Power (LADWP) and Sacramento Municipal Utility District (SMUD) together represent over half (55.1%) of all public power retail sales. On the other end of the spectrum, the 23 smallest POUs constitute about 1/10 of the retail sales of LADWP and SMUD (5.9%). With regard to the total retail sales for the state, including investor owned utilities, the 23 smallest POUs constitute only 1.6% of statewide retail sales. In general, larger utilities serve a more diverse customer base and offer a larger portfolio of incentives and rebates. In contrast, smaller utilities with fewer overall customers and customer types focus on fewer programs that best fit their particular customer needs. Annual retail sales are a relative indicator of a utility’s resources for managing energy efficiency programs. Program administration can be a challenge for smaller utilities with limited resources. In some cases, a POU may have a single staff member manage their energy efficiency programs, among other duties. The collaborative nature of the public power community allows for the development of joint resources and sharing of best practices. CMUA, NCPA, and SCPPA serve as forums for discussing and pursuing projects on behalf of groups of or all POUs. The tools developed to support this report’s compilation are an example of public power collaboration.


Customer Economic Factor s Customer economic factors also inform public power decisions regarding energy efficiency programs. Many POUs serve low-income communities in which unemployment is relatively high and the median income is low. POUs that serve rural communities in the inland and northern parts of the state tend to have higher unemployment rates compared to Bay Area and LA metro areas. Figure 4. Unemployment Rate by POU, 2016

Income is one of the most critical factors influencing the programs a POU offers to its customers. Low-income customers typically have limited disposable funds and access to capital, so higher incentives will be necessary to support low-income customers for energy efficiency improvements. Low-income renters in multifamily dwellings face additional challenges as the building owner, not the customer, frequently determines whether energy retrofits are made to the building. Figure 5.

SB 350 provided a bold vision for California – to double the energy savings from energy efficiency by 2030. This goal is the latest addition to California’s suite of programs advancing energy efficiency. SB 350 identifies a number of these current policies as sources of energy savings, including public power customer programs, needed to achieve the statewide target.

These policies, when coordinated, work together to facilitate customer investments in energy efficiency. Public power actively participates in the many energy efficiency forums to provide perspective from our diverse communities. POUs look forward to continuing to work with the Energy Commission and the growing universe of stakeholders on the successful implementation of these programs.

Public power programs support the statewide effort to double energy savings by 2030.


METHODOLOGIES

This section provides a brief overview of the technical resources and analytical tools used or developed by public power to evaluate its energy efficiency program and develop energy efficiency targets. Database for Energy Ef f icient Resources The California Public Utilities Commission (CPUC) oversees the development of the Database for Energy Efficient Resources (DEER) to provide estimates of energy and peak demand savings values, measure costs, and effective useful life (EUL) for measures. While DEER primarily exists to inform IOU programs, POUs historically relied on DEER for consistency. However, a number of stakeholders, including the IOUs, have expressed concerns with the DEER database in recent years. Due to DEER deficiencies, IOUs increasingly rely upon workpapers that are more representative of their actual results. The DEER database continues to provide energy savings estimates for many measures that align with results from POU EM&V reports. However, for some programs, DEER savings estimates are not consistent with the actual results, so POUs must rely on other sources or studies. Furthermore, the process for updating DEER measures, and the basis for making these changes, is opaque and complex. For more information on DEER, visit the CPUC webpage: http://www.deeresources.com/

Technical Reference Manual Recognizing that the DEER database is not a viable resource for public power to continue to use, in 2013 POUs contracted for the development of a technical reference manual (TRM) modeled after the Northwest Regional Technical Forum resource. Public power retained Energy & Resource Solutions (ERS) to develop the TRM to be used by utilities across the state’s different building climate zones. ERS completed the TRM in 2014 and an update in 2016. The TRM has replaced DEER as the basis for which most POUs calculate the energy savings of their programs. The TRM provides the methods, formulas, and default assumptions used for estimating energy savings and peak demand impacts from energy efficiency measures and projects in a very clear and open format. POUs use the energy savings estimates to report program accomplishments and measure progress towards program goals. Energy efficiency measures are documented and classified as either unit energy savings (UES) measures, semi-custom measures, or custom measures. The TRM includes both nonresidential and residential measures, and presents each measure type in separate sections, grouped by technology type.

http://www.deeresources.com/


The TRM includes the main manual as well as supporting spreadsheets. The TRM also includes spreadsheets that provide detailed and transparent measure calculations and, for semi-custom measures, energy savings calculators for estimating energy savings for project-specific measures. As needed, each section also contains supplementary tables and charts to provide additional measure details. Measures with multiple savings values (savings by size, building use, varying levels of efficiency, etc.) will have both savings and cost data listed in a supplementary table. The last section of the TRM provides the custom measure protocol, which outlines a process for estimating and documenting custom measure savings. The TRM includes energy savings calculators, which are Excel spreadsheet-based engineering models for estimating semi-custom measures per the described methodology. They provide a consistent, transparent, and user-friendly approach for estimating project-specific energy savings. The TRM provides a much higher degree of transparency for public power, policymakers, and interested stakeholders regarding the energy savings estimates underpinning public power’s energy efficiency programs. For more information on the 2016 TRM, visit the CMUA webpage: http://cmua.org/energy-efficiency-technical-resource-manual-2016/ Energy Ef f ic iency Repor ting Tool Energy and Environmental Economics (E3) designed the Energy Efficiency (EE) Reporting Tool for POUs to analyze and report on the

energy savings results from energy efficiency programs. POUs may also use the tool to analyze the savings from potential new programs and determine whether they are likely to prove cost effective. The EE Reporting Tool contains the TRM database of energy efficiency measures. POUs select the measures that reflect their programs and enter the relevant data. E3 designed the EE Reporting Tool to minimize the data input required by the utilities. Relying on default TRM values and assumptions, POUs may enter as little as the number of units installed, the incentive provided to the customer and overhead costs to report meaningful results. Alternatively, utilities may modify or enter their own assumptions and create customized measures that best reflect their programs or service territory. The EE Reporting Tool then provides summary tables by program category that report the units installed, achieved savings, program costs and cost effectiveness. E3 maintains the Distributed Energy Resources Avoided Cost Model and E3 Calculator adopted by the CPUC to report on the cost-effectiveness IOU programs. The EE Reporting Tool is a simplified version of that model that uses the same avoided costs and cost-tests adopted by the CPUC. Avoided costs and EE measure load shapes in the EE Reporting Tool are represented using six time-of-use periods (rather than 8,760 hourly resolution). In addition, the TRM measures are a consolidated and representative subset of the much larger number of measures in the DEER database. Both of these simplifications

make the model much simpler and user-friendly for the diverse range of public power utilities. Electr ic Resource Assessment Model POUs contracted with Navigant Consulting, Inc. (Navigant) to support their efforts to identify all potentially achievable cost-effective electricity efficiency savings and establish annual targets for energy efficiency savings for 2018-2027. Navigant utilized the Electric Resource Assessment Model (ELRAM) to develop estimates of technical, economic, and market potential for each POU. The ELRAM is substantively similar to the Navigant model used by the CPUC to establish annual targets for the IOUs. POUs worked with Navigant in 2012 to develop 2014-2023 annual energy efficiency targets. Navigant used ELRAM for both the 2012 and current targets. The new ELRAM is more powerful in its computational capabilities and agile in its scenario development capabilities. It also now includes a robust and easy to use output viewer, which allows the client to view potential savings estimates in a variety of ways without loading the entire ELRAM. For additional background on the ELRAM and the technical assumptions of the model, see Append ix B . Evaluation, Measurement & Verif ica tion Section 9505(d) of the Public Utilities Code requires each POU to make available to its customers and to the Energy Commission the results of any independent evaluation that measures and verifies the energy efficiency

savings and the reduction in energy demand achieved by its energy efficiency. The Evaluation, Measurement & Verification (EM&V) process used to provide POU program managers with feedback relies on the approaches articulated in the National Action Plan for Energy Efficiency, adopted CPUC protocols, and the innovation and expertise of firms experienced in program evaluation. In addition, public power worked with the Energy Commission to develop a consistent set of EM&V guidelines for third-party consultants retained to evaluate utility programs. EM&V reports help to define the effectiveness of individual programs with the intent of improving future offerings. Key findings from the EM&V reports confirm high realization rates for reported energy savings. This indicates that this annual report provides a reliable source of data to help policymakers gauge the progress of the state’s overall energy efficiency efforts. At the time this report was published, the public power community had made available more than 80 separate EM&V studies. To review the EM&V reports, visit the NCPA webpage: http://www.ncpa.com/policy/reports/emv/ A number of utilities are currently in the process of completing EM&V studies for FY2015-2016 programs. These and other subsequent EM&V reports will be posted to the above URL as they become available.

PROGRAM RESULTS

This section provides an overview of the energy efficiency program results for public power in California. Append ix A contains detailed review of each POU’s program descriptions, expenditures, and energy savings. Most POUs manage programs on a fiscal year basis and programs results reported are for FY 2015-16. For Imperial Irrigation District, Merced Irrigation District, Modesto Irrigation District, Plumas-Sierra REC, SMUD, Truckee Donner PUD, and Turlock Irrigation District, results are for calendar year 2016. Figure 6 provides a comprehensive summary of energy efficiency program savings for all POUs. LADWP alone represents nearly half (49.9%) of the total gross annual energy savings for public power. Figure 7 reviews results by program category. Excluding Codes and Standards, lighting programs once again account for the largest share of the gross annual energy savings (39.2%), although the share of savings attributable to lighting continues to decrease. Two years ago, lighting represented over half (52.5%) of POU program savings (excluding Codes and Standards). At the same time, compared to FY 2013-2014, the total gross annual energy savings (excluding Codes and Standards) has increased by over 20,000,000 kWh, indicating that POU programs are achieving savings “beyond the bulb”.

Figure 8 provides data for the utilities subject to the integrated resource plan requirements of SB 350. These 16 utilities provided 97.3% of the public power’s gross annual energy savings, which is roughly these utilities’ share of POU retail sales (94.1% in CY 2015). Figures 9, 10, and 11 summarize program results since the first annual report in 2006. During the 2016 reporting cycle, POUs spent over $154 million on programs, resulting in more than 825,000,000 kWh of gross annual energy savings. When added to the total investments since the signing of SB 1037, public power has spent over $1.37 billion on energy efficiency and achieved nearly 63.6 billion kWh in lifecycle energy savings. As a whole, public power is becoming more efficient at energy efficiency. From 2014 to 2016, the gross annual energy savings from programs (excluding Codes and Standards) grew by 3.7%, while program costs declined by 11.3%. Driving these trends was increased customer participation in residential and commercial comprehensive programs, such as direct install and whole building retrofits. Customer rebates account for the overwhelming majority of program expenditures (77.1%), with the remaining costs (22.9%) dedicated to utility marketing, administrative and reporting costs, as well as evaluation, measurement, and verification (EM&V) efforts.

The need for public power support of Title 24 is increasing as the state moves to zero net energy homes by

2020, and non-residential buildings by 2030. However, POUs wish to avoid confusion as the Energy Commission also accounts for energy savings from Title 24. Previous annual reports did not differentiate between support for Title 24 and customer incentive programs and as such, Figure 8 provides corrected totals.

POLICY CONSIDERATIONS

The past year brought many challenges and new opportunities for public power programs. As the California energy efficiency policies and market evolve, POUs continue to innovate and develop programs tailored to the changing needs of their community. As the state looks to double the

energy savings from energy efficiency by 2030, the ingenuity and collaborative spirit of public power will be even more critical. The continued success of the past year provides an excellent foundation on which public power looks to build upon.


In the development of updates to Title 24 Building Energy Efficiency Standards, the Energy Commission evaluates the cost-effectiveness of proposed mandatory measures and prescribed measures. Essentially, if the cost to comply with a measure is less than the value of energy that otherwise would have been consumed over the lifecycle of the measure, then the measure is deemed to be cost-effective. For Title 24 measures, the lifecycle is 15-30 years. POUs, in procuring energy to serve its customers, are directed to first acquire all available energy efficiency and demand reduction resources that are cost effective, reliable, and feasible.2 The levelized utility cost (i.e., $ per lifecycle MWh saved) of energy efficiency measures provides the most useful metric for evaluating cost-effectiveness and for making comparisons to generation resources. For POU programs, the lifecycle, or expected useful life, of many measures ranges from 5-15 years. Return on investment (ROI) best defines cost-effectiveness from a non-residential customer perspective. According to a Siemens survey of commercial facilities executives,3 54% responded that the payback period for energy efficiency projects needed to be 5 years or less; only 3% said 6-8 years or less, and another 3% said 9 years or more.

2 Cal. Public Utilities Code § 9615 and § 454.5(b)(9)(C). 3 Siemans / Building Operating Management. August 2010. Economic of Energy Upgrades – Breaking Through Barriers.

In many cases, a residential customer’s decision to make energy efficiency improvements is not primarily motivated by reducing their monthly utility bill or a specific attitude towards energy efficiency. Arthur Rosenfeld, former CEC Commissioner and renowned as the “godfather of energy efficiency”, co-authored research that framed customer motivations as follows:

From a consumer perspective, it is often the non-energy benefits [i.e., improved indoor environment, comfort, health, and safety] that motivate (or can be used to promote) decisions to adopt energy-efficient technologies… From the perspective of energy consumers, non-energy benefits can equal or even exceed the importance of the energy cost avoided, thus meriting greater consideration in private investment decisions, marketing strategies, design and evaluation of utility programs, and government policies designed to promote energy efficiency.4

Understanding customer value propositions for energy efficiency is particularly relevant when developing policies and programs targeting energy savings in existing buildings; 15-30 year payback periods for a project will probably not attract high levels of customer interest.

4 Mills, E. and Rosenfeld, A. 1996. “Consumer Non-Energy Benefits as a Motivation for Making Energy-Efficiency Improvements.” Energy (21)7-8: 707-720.

Customers, utilities and policymakers define “cost-effectiveness” differently.


Whereas non-energy benefits can motivate customers to invest in energy efficiency, transaction costs can deter participation. An Energy Institute at Haas working paper5 explored the impact of non-monetary costs on customer participation in a free weatherization program. The Weatherization Assistance Program study provided participating households with an energy audit and a home retrofit that typically included some combination of insulation, window replacements, furnace replacement, and infiltration reduction. The average value of the efficiency retrofits provided to participating households in the study exceeded $5,000 per home. The research found that the process of applying for weatherization programs is onerous and time intensive. Applicants must submit extensive paperwork documenting their eligibility. Despite being eligible for an average of $5,000 in improvements, the paper concluded that there is “striking evidence that individuals and households bypass opportunities to improve energy efficiency that require zero out-of-pocket expenditures and are widely believed to be privately beneficial.” The researchers also noted that participation only modestly increased by extraordinary education and outreach efforts.

5 Fowlie, M., Greenstone, M., and Wolfram, C. 2015. “Are the Non-Monetary Costs of Energy Efficiency Investments Large? Understanding Low Take-up of a Free Energy Efficiency Program.” Energy Institute at Haas WP 256.

The rate at which households pursued a weatherization retrofit increased nominally from less than 1% to almost 6% when provided the additional education and outreach. On average, it cost an additional $1,000 per household in program administration for the education and outreach efforts. In a similar vein, the SB 350 Low Income Barriers Study notes that the processes associated with securing energy efficiency financing can be onerous for customers and may pose major obstacles to participation. These hurdles limit a customer’s interest in securing financing. Low-income working persons, many of whom already find their time and energy spread thin, could find these hidden costs to participating in energy retrofit programs untenable.6 Public power supports the SB 350 Low Income Barriers Report recommendation seeking greater coordination of state agencies administering energy and related programs for low-income customers and disadvantaged communities. POUs welcome efforts to align eligibility requirements and reduce redundancies and administrative overhead, particularly if this effort encourages collaboration, standardization, streamlining, integration, and co-funding opportunities across government agencies.

Complicated application processes deter customer participation in programs.


The challenge and complexity of achieving a doubling of statewide energy efficiency savings by 2030 cannot be understated. Failure to accurately assess and incorporate customer perspectives may lead to the establishment of annual targets for statewide energy efficiency savings that grossly mischaracterize energy efficiency market and economic potential. Whereas programs, such as the Title 24 Building Energy Efficiency Standards, and utility incentive programs, have established methodologies for forecasting potential energy savings that consider customer acceptance and participation, other non-utility programs and market activities have not been previously modeled. SB 350 directs the Energy Commission to establish annual targets for statewide energy efficiency savings based on additional achievable energy efficiency (AAEE) savings, which captures the energy efficiency potential for investor owned utilities, and public power’s 10-year energy efficiency potential studies. Taken together, AAEE and the POU potential studies model all cost-effective and feasible energy efficiency program savings for utilities. In order to achieve a statewide doubling of energy efficiency savings, nonutility programs, which do not factor into the AAEE or POU potential studies, must be a significant source of new energy efficiency savings.

The strategies outlined in the California’s Existing Buildings Energy Efficiency Action Plan (EBEE Action Plan), “aim to mobilize market-based activity in California such that the existing $1.1 billion in annual ratepayer-funded programs is leveraged to activate sufficient private capital to reach an annual investment of at least $8 billion per year.” As such, the EBEE Action Plan plays a critical role in setting annual statewide targets and achieving the doubling of energy efficiency savings by 2030. To this end, the Commission will need to develop forecasts for the anticipated energy and demand savings, as well as the costs and benefits, for each of the strategies outlined in the EBEE Action Plan to include in the statewide energy efficiency savings doubling targets. In contrast to the robust modeling completed for utility programs, public power is unaware of forecasts of the energy efficiency savings and demand reduction potential for a number of nonutility programs, including the EBEE Action Plan, the California Clean Energy Jobs Creation Act, the Building Energy Use Benchmarking and Public Disclosure Program, and Property Assessed Clean Energy (“PACE”) programs. Public power strongly encourages the Energy Commission to prioritize their resources towards modeling the energy efficiency savings from nonutility programs. Without this data, it is not possible to set meaningful annual statewide targets as required by SB 350.

Non-Utility programs are essential to achieving the 2030 Doubling of Energy Efficiency Goal.

Cost Summary


ALAMEDA MUNICIPAL POWER Alameda Municipal Power at a Glance

• Climate Zone – 3A • Number of retail customer connections – 35,336 (88% residential, 12% commercial) • FY15-16 total retail sales - $53,759,746 ($19,869,104 - residential,

$33,890,642 - commercial) • FY15-16 total budget for energy-efficiency programs - $1,973,000 • FY15-16 total amount actually expended for energy-efficiency programs - $1,463,831

Alameda Municipal Power Overview

• Due to Alameda’s temperate climate and small amount of industry, the peak demand for electricity is in the winter (December and January) in the early evening. AMP’s electric load is relatively flat compared to most California utilities and there is no residential air conditioning.

• More than 9% of AMP’s load is maritime, which includes a Coast Guard Base, the Maritime Administration with nine ships home ported in Alameda, and a large ship yard.

• In FY 2016 AMP finished installing advanced metering infrastructure (AMI) on its 300 largest commercial customers and about 1,700 residential customers. The AMI commercial customers have access to a portal with their energy-use data, including 15-minute interval data, kW, kWh, kVA, power factor, and weather data. Complete build out for all AMP customers will be completed in 2018.

• AMP has committed to spending much of our cap-and-trade and renewable energy credit (REC) funds to reduce greenhouse gas emissions in its service area.

• The average residential energy use has been declining annually since 2011. With the exception of FY 2016, total energy sales have been decreasing also. This trend is similar to other utilities both in California and nationally.

AMP Electric Sales and Average Residential Electric Use

Year Actual Electric Sales (MWh/yr.)

Residential Average Annual Electric Use

(kWh/yr.)

2011 382,634 4,651 2012 373,787 4,555 2013 363,444 4,434 2014 353,913 4,265 2015 342,203 4,053 2016 348,820 3,989

• This downward trend is likely due to several factors, including: • Increase in customer energy efficiency • Increase in customer-owned distributed generation • Increase in energy efficiency in codes and standards, particularly CA Title 24 – the

CA Building Standards, and Title 20 the 2012 Appliance Efficiency Regulations • Decreased energy use in consumer products. For example, LED TVs , which use 130

watts, have largely replaced plasma TVs, which used 400 watts. Also lap top computers, which use 5 watts, have largely replaced desktop computers, which used 32 watts.

• Increase in the efficiency requirements for the Energy Star label Major Program Changes

• Residential LEDs: AMP offered three different LED rebates in FY 2016. The first was a continuation of LED MANIA, a mail-in rebate offer from FY 2015 with very attractive rebates. This program concluded with products purchased on July 31, 2015. Next, AMP participated in an upstream program with other Northern California Power Agency (NCPA) member utilities. This program ran from February through May. Finally, AMP’s online rebate program went live in March with rebates for LED bulbs and fixtures.

• Residential Online Rebates: In March 2016, all residential rebates were moved to an online system. The $45,000 program set-up fee were a major contributor to the administration costs for this fiscal year. AMP expects to see lower administration figures for the online rebate program in FY 2017. The online rebate program allowed AMP to add new rebate categories, including electric clothes dryers, washing machines, and heat pump water heaters.

• Non-residential Direct Install Programs: The Commercial Lighting Program ended December 2015. Based upon the success of that program, AMP started the Energy Plus Program to include all non-residential customers and refrigeration measures.

Program Highlights

• Total residential sector lighting savings was nearly 235 MWh (gross). Alamedans purchased more than 12,000 LEDs in FY 2016 – 40% of all residences could have installed a new LED. In FY 2015, customers purchased or received nearly 60,000 LEDs. AMP will continue to promote LEDs to residential customers, though it is expected that growth will slow as LEDs have become ubiquitous in Alameda. LEDs were purchased through three venues: LEDMANIA, a mail-in rebate program, the upstream, or Instant Rebate program, or AMP’s new online rebate.

o LEDMANIA, AMP’s mail-in rebate program, was only available for one month, and was just the continuation of a short-term program offered in FY 2015.

o The upstream program was very successful and offered from February to July. Customers purchased more than 7,500 LEDs during this five month period. There is some concern that a small percentage of these LEDs were installed outside of Alameda, but AMP also recognizes that with Alameda’s proximity to Pacific Gas &

Electric’s (PG&E) territory, it is very likely that Alamedans also purchased LEDs from PG&E’s upstream program. AMP may consider repeating this program during another year. AMP’s online rebate program started in March 2016. In its first four months, more than 100 LEDs and fixtures with integrated LEDs have been incentivized. Rebates are lower than the mail-in rebate, which reflects recent decreases in LED prices. AMP expects to see continued participation in this program over time.

• Commercial Lighting Program A direct-install lighting program, the goals of the program were to remove customer barriers to lighting retrofits such as knowledge of lighting technologies, project management, quality of contractors and fair pricing, first costs, compliance with Title 24, and reach customers that have not participated in energy efficiency programs previously. The majority of the lighting retrofits were LEDs replacing various high-intensity discharge fixtures. More than 70% of the participants were small commercial customers who had never participated before in efficiency programs and the program rebates covered an average of 56% of the project cost. With a budget of $600,000 the Program resulted in energy savings of 1,660 MWh/year and a demand savings of 406.8 kW.

• Energy Plus Program Based upon the success of Commercial Lighting Program, AMP started the Energy Plus Program in FY 2016 with a budget of $1.1 million to include all non-residential customers and refrigeration measures. This direct install program has a goal of 3,013 MWh energy savings and will run for two years or until the funds expire.

• Street Light Retrofit The LED retrofit of all Alameda cobra head and shoebox street lights, 3,202 lights, was completed resulting in savings of 868,224 kWh per year. The annual energy cost savings for retrofitting the 3,202 fixtures is $203,346, and the AMP rebate was $86,822.36. The remaining historic and decorative street lights, 1,877 lights, will be retrofitted with LEDs in FY 2017 and 2018.

Program Descriptions Residential Lighting

• LEDMANIA: AMP offered two LED rebate programs in FY 2016. The first, a mail-in rebate program, LED MANIA, was closed to purchases made after July 31, 2015. LED MANIA’s rebates were available for both fixtures and lamps--$5 for LEDs less than 1,000 lumens and $10 for 1,000 lumens and greater.

• LED Upstream Program: AMP partnered with other NCPA utilities and local Alameda retailers to offer pre-rebated LEDs. This program, which AMP called the Instant Rebate program, ran from February through July (meaning that one month of this program will be captured in FY 2017). The program offered five types of LEDs: a candelabra, BR 30 flood, and A-lamps with 800, 1100, and 1600 lumen outputs.

• Online Rebate Program: AMP launched their online rebate program in March 2016. This program offers different rebates for LED lamps and fixtures. Lamps are rebated at $3 if

less than 1,000 lumens and $10 if 1,000 lumens and greater. Fixture rebates are set at $8, and $15, respectively.

Residential Refrigeration

• Energy Star Refrigerator and Freezer Rebate & Recycle Program: This program provides a $100 rebate to customers who purchase an Energy Star refrigerator or freezer and recycle their old appliance with AMP’s recycler. Part of the goal of the program is to educate customers about Energy Star and encourage the purchase of other Energy Star appliances and equipment. AMP expects this rebate amount to decrease in FY 2017. Other utilities may limit this rebate to just the higher Consortium for Energy Efficiency (CEE) Tier 2, 3, 4, or Advanced levels. AMP continues to rebate based on Energy Star certification alone as a means of simplifying the program for participants, as well as keeping the program open to lower income residence.

• Second Refrigerator or Freezer Pick- Up Program: This program provides customers a $35 rebate to get rid of their extra refrigerator or freezer and recycle it properly with our recycler.

Residential Appliances

• Energy Star Electric Dryer: AMP’s new online rebate program includes electric clothes dryers, which are eligible for a $100 rebate. Since March, four new units have been installed.

• Energy Star Washing Machine: Also new, this program offers electric-only customers a $150 rebate on Energy Star washing machines. As with refrigerators, this program is available for all Energy Star-certified washing machines. Customers that have natural gas service are not eligible for this rebate. AMP has not yet had any customers participate in this incentive.

• Energy Star Heat Pump Water Heater: The final new addition to AMP’s online rebate program incentivizes customers to upgrade to a new Energy Star-certified electric heat pump water heater. Like the washing machine incentive, AMP has not had any customers participate in this program, despite a $500 rebate opportunity.

Residential Other • Monitor Lending Program: Borrow a Kill A Watt monitor to measure the energy use of

appliances. • Onsite Energy Audits: Residential audits at no cost. • Online Energy Audit: Online residential energy audit and associated tools such as an

appliance calculator and energy library on AMP’s website. • My Energy Program: As part of the My Energy program a home energy report is mailed

to 50% of Alameda residential customers every two months that includes a summary of the homes’ historical and recent energy use, energy efficiency tips, and a comparison of their energy use to their neighbors. This program will close in December 2016.

Non-residential Direct Install Programs • Commercial Lighting Direct Install Program: Started in FY 2015 and ended December

2015 (FY 2016) the Commercial Lighting Direct Install Program was administered by a third-party vendor.

• Energy Plus Program: The Energy Plus Program is an expansion of the Commercial Lighting Direct Install program that includes all non-residential customers and refrigeration measures. The program started in January 2016, funded for $1.1 million, is expected to run for two years.

Non-Residential Cooling

• Commercial HVAC Retrofit Program: Prescriptive rebates for retrofitting existing buildings with energy-efficient HVAC equipment.

Non-Residential Lighting

• Commercial Lighting Retrofit Program: A program with rebates, both prescriptive and custom, for retrofitting lighting with energy-efficient equipment.

Non-Residential Process

• Commercial Customized Rebate Program: A program with customized rebates based upon the kWh/year savings not covered by the lighting or HVAC program

Non-Residential New Construction

• New Construction Design Assistance: Grants of up to $10,000 for energy-efficient design work.

• New Construction Rebates: Whole building and systems rebates for energy-efficient new construction.

• Commercial On-Site audits: Free energy audits for lighting, HVAC, refrigeration, process systems, etc.

EM&V AMP completes the evaluation, measurement, and verification (EM&V) process every two years. This method is an economical use of staff resources. The most recent EM&V focused on three FY 2015 residential programs. The typical budget for EM&V is $40,000 for two years. The next EM&V will be for FY 2016 and 2017 and may focus more on commercial programs. The following three programs were studied:

• “Great Light Bulb Change Out:” All residential service addresses in Alameda were mailed two 800 lumen LEDs, packaged as a gift from AMP. Alamedans received their LEDs February – March 2015. Residents were encouraged to replace their high-use incandescent lights with these new long-lasting energy-efficient LEDs.

• LEDMANIA: After customers received their LEDs in the mail, AMP simplified their LED rebate process. The pre- and post-install and savings based on kWh savings was replaced with a prescriptive rebate and a simple mail or email application.

• Refrigerator/Freezer Recycle Program: This program encourages Alamedans to disconnect and remove an extra refrigerator or freezer. AMP arranges a pick up (and proper recycling) of the old appliance and provides a rebate to the customer.

The following are highlights of the EM&V study:

• The installation rate for the Direct Mail Lighting Campaign is high. 90% of those surveyed indicated that the LED light bulbs provided by AMP were installed.

• The reported energy savings for the Direct Mail Lighting Campaign is a conservative estimate of the actual savings achieved. Verified savings indicate a 175% realization rate, but this estimate is likely overstated due to uncertainties associated with preexisting lamp sizes reported by customers.

• The installation rate for the LED Rebate Lighting Program participants is also high; 89% of the lamps expected to be installed were verified on-site. The verified savings for these participants is 114,785 kWh. Compared to the reported savings of 115,389 kWh, the realization rate is 99.5%.

• The refrigerator recycling program verified savings for program year 2015 is 7,392 kWh with a realization rate of 57%. Verified savings are based on recycler records, which were incomplete and likely underrepresent the number of recycled refrigerators.

• Customer satisfaction with the LED light bulbs installed was generally very high. • The majority of customers across both lighting programs were satisfied with the LED lamps

installed, including the quantity and quality of light emitted.

The EM&V study helped inform staff’s need to keep records for the freezer and refrigerator hauler/recycler. AMP will now send a yearly electronic back up of pick up information back to the hauler because a member of their staff was regularly disposing of paper records. The high realization rate (99.5%) for the LED Rebate Lighting Program creates confidence in AMP’s unique a baseline of one-third compact fluorescent and two-thirds incandescent as existing. This data shows that Alamedans have not moved to halogen incandescent lighting. AMP expects to update this to match the “Technical Resource Manual” (TRM) in future program years. The report can be found here. Sources of Energy Savings With a goal of getting the most accurate energy savings, AMP staff used a variety of sources. For the residential lighting energy savings, AMP used historical AMP customer program data, buoyed by a high realization rate in the FY 2015 EM&V report. The energy savings figures for the residential refrigerator programs were from the “Technical Resource Manual” (TRM 2016) for the CA Municipal Utility Association. The electric clothes dryer savings was from an Energy Star

http://media.alamedamp.com/assets/PUB/2016/07/16-0718-5A-Res-EE_CO.pdf

report. Energy savings from My Energy, AMP’s residential behavior program, were from actual AMP billing records and compared the test group, those that received the printed HER, to the control group that did not receive HERs. Opower, the vendor responsible for My Energy, handled these calculations. The City of Alameda Public Utilities Board requested that staff use a net-to-gross ratio of 1.0 for the My Energy program. All of the energy savings from the commercial lighting measures are from the actual pre- and post-installation inspections. The energy savings from the refrigeration retrofit and the variable frequency drive were from the TRM 2016. The energy savings from the commercial new construction projects were from the Title 24 reports and the TRM 2016, and all were field-verified. Lastly, the commercial HVAC energy savings for the chiller retrofit were based upon calculations from Salas O’Brien Engineers. Complimentary Programs

• Renewable Energy Programs: Alameda Green, AMP’s voluntary green power program, provides customers with the option to choose 100% renewable energy at an additional cost of $0.015/kWh. As of the end of FY 2016, there were 2,113 residential and 70 commercial customers enrolled in Alameda Green. AMP staff encouraged enrollment through Alameda Green mentions in AMP’s customer newsletter, four bill inserts, social media, an outreach program, “Shop Clean & Local” week during Public Power Week, and a contest among customer service representatives. In May 2016, AMP earned a national ranking for green utility programs from the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL). AMP’s “Alameda Green” program made NREL’s “Top 10” list for its high participation rate in 2015.

• Low-Income Programs: AMP continues to provide financial assistance to Alameda's low-income families through the EASE (Energy Assistance through Supportive Efforts) and EAP (Energy Assistance Program) programs. For FY 2016, EASE, an emergency relief program, helped 82 households receive a total of $7,078.12 in electric bill assistance. A maximum amount of $200 is available per household within a three-year period through the EASE program. The EAP provides a 25 percent monthly discount on the electric bill. A total of $73,973.46 was allocated to 601 Alameda households. These programs are funded through the public purpose component of AMP's energy charge.

• Electric Vehicles: In FY 2016 there were a total of 381 AMP customers registered to receive the electric vehicle (EV) discount, up from 291 registered in FY 2015 and 58 in 2014. AMP purchased two EVs and one plug-in hybrid for fleet vehicles in FY 2016.

• Energy Storage: AMP does not have any onsite storage and an evaluation of energy storage was done in 2014 as required by California AB 2514. The evaluation concluded that energy storage was not cost effective at this time. However, AMP continues to evaluate the potential for this technology.

ANAHEIM PUBLIC UTILITIES

Anaheim Public Utilities at a Glance • Established in 1894 • Climate Zone 8 • 181,440 meters. 117,593 are electric and 63,847 are water • Percent of electric retail sales by customer class - 25.7% residential, 34.2% commercial,

36.8% industrial and 3.4% miscellaneous • Budgeted amount for energy efficiency programs: $5,052,599 • Amount expended: $4,731,858 • Funding source: Electric Revenue

Anaheim Public Utilities Overview Anaheim Public Utilities (APU) provides electricity and water to a community of 358,000 residents, over 10,000 businesses and more than 25 million annual visitors over an area that covers more than 50 square miles. The Anaheim Resort, Anaheim Canyon and the Platinum Triangle account for a large proportion of the energy and water consumed in Anaheim, and contribute significant energy use and tax based revenues to the City's General Fund. There was a continued growth and economic development in FY15-16 and it is anticipated that approximately $4.5 billion will be invested in the Platinum Triangle and Anaheim Resort areas in the next 2 years. Four new hotels were completed in the Anaheim Resort Area in 2016. The Anaheim Convention Center has made great progress in the 200,000 square foot expansion to increase the number of convention shows and visitors to the City; its anticipated completion date is Fall of 2017. In FY15-16, nearly 800 new apartments and condominiums were completed and over 2,100 dwelling units are under construction in the Platinum Triangle. At full build out, the Platinum Triangle will be host to 28,000 residents, 19,000 apartments and condominiums, 14 million square feet of office space and 4.7 million square feet of commercial, retail and hotel space. The California 2013 Title 24 Building Energy Efficiency Standards continued to impact the quantity and types of energy efficiency projects undertaken by APU customers, particularly in the area of commercial lighting projects. The increased costs for additional equipment and controls resulted in fewer large scale commercial lighting retrofits in fiscal year 2015-16.

APU customers continued to pursue their interest in alternative sources of electricity to meet their personal and business needs. This was achieved predominantly through the installation of solar energy systems. APU estimates that over 2,500 solar energy systems totaling about 25 megawatts will be built throughout Anaheim by the end of 2017. Fuel cells are also making their impact in Anaheim with a number of large commercial customers installing or considering the installation of systems to

offset their load, some as much as 50% or more. While APU strongly recommends that customers incorporate energy efficiency into their overall property performance prior to installing a solar system or a fuel cell, customer interest in alternative energy sources remains high.

Major Program Changes APU modified its energy efficiency program portfolio in FY15-16 to take advantage of the successful partnering with the Southern California Gas Company by doubling the funds allocated to this income qualified program. Income qualified customers receive the value of a one stop approach that provides electric, gas and water savings through a host of resource efficiency measures, equipment and appliances.

Program Highlights APU's Customized Energy Incentives Program provides its commercial and industrial customers with the greatest flexibility in selecting energy efficiency projects that provide them with the greatest return on their investment. Customers appreciate the opportunity to select improvements that are specific to their operation, particularly if their greatest energy savings strategies may not be for measures that fall into a prescriptive menu. In addition to the incentives offered for new construction and retrofit applications, customers can also receive a free specialized or comprehensive energy audit for their facility. This assists them in identifying the greatest energy consuming end uses as well as the energy savings potential and payback for their investment. This comprehensive approach provides the greatest overall energy savings for our customers and provides APU with a significant contribution towards its overall energy savings goal.

In the partnership with the Southern California Gas Company, both utilities benefitted from the jointly delivered programs and services to their mutual customers. The working relationship between the two utilities streamlined implementation, facilitated the use of common contractors to implement electricity, water and natural gas efficiency measures, and allowed the utilities to cross-promote each other’s conservation programs.

CITY OF BANNING City of Banning At a Glance

• Established in 1922. • Climate Zone 15 • 27 employees. • Of the 12,111 customers, 91% are residential • Average demand during FY 15/16 was 16.75 MW, down 0.3% from the prior period. • Peak demand during FY 15/16 was 44.5 MW, up 4.9% from the prior period. Peak

demand is primarily due to air conditioning load during the summer. • Retail energy sales in FY 15/16 were 139,950,565 kWh, down 3.5% from the prior

period. Retail sales are broken down as 48 percent residential and 52 percent commercial/industrial/institutional.

City of Banning Overview During FY 15/16, Banning spent $167,480 in Energy Efficiency programs, which have provided 319,202 kWh energy savings. It should be noted that the City of Banning is located in an economically disadvantaged area. A significant portion of the City’s population is either low income or senior citizens living on a fixed income. Due to the economic demographics of Banning’s population, a significant portion of Public Benefits dollars are utilized to provide low-income assistance through reduced rates. Major Program Changes One of Banning’s main goals for FY 2015/16 is to expand participation in its commercial retrofit and refrigeration programs, primarily through the adoption of significantly increased monetary incentives for our small commercial businesses. To accomplish this goal Banning increased the budget and worked with community organizations to further increase awareness and overall participation of the Business Energy Efficiency Funds, or “B.E.E.F” program. Program Descriptions

• Business Energy Efficiency Fund: Monetary incentives for commercial customers to install energy efficiency upgrades/retrofits such as lighting, refrigeration, motors, air conditioning tune-ups, etc.

• Air Conditioner: Monetary incentives to replace an existing central air conditioning unit with a new high-efficiency unit.

• New Construction: Monetary incentives for new construction projects that exceed the energy efficiency above California’s Title 24 standards.

• Energy Audits: Provides customers with a variety of recommendations for reducing energy consumption.

• Low Income Assistance: An electric utility reduced Baseline Rate for qualified customers. As mentioned above, a large portion of the Public Benefits funds are spent providing low-income assistance.

EM&V The City of Banning Electric Utility has hired third-party firms, such as Lincus, Inc., to perform EM&V studies in previous years. The City will continue with its EM&V programs and practices. Complimentary Programs Renewable Portfolio Standard. The City of Banning is set to reach greater than 70 percent renewables by 2018. In support of this goal, Banning is doing all of the following:

• The City has contracted for geothermal energy from two generating facilities. Together they supply approximately 19 percent of the City’s energy need.

• The City has reached an agreement to divest itself of its interest in the San Juan Generating Station Unit 3 by December 31, 2017. Once this divestiture is complete, the City will be replacing this coal-based energy with renewable energy. The City has already entered into long-term renewable energy contracts that will increase the City’s renewables to greater than 70% of retail sales by 2018.

• Banning has met its California SB1 requirements by providing $2.4 million in rebates for the installation of solar photovoltaic systems in its service territory. The rebates have helped install approximately 0.75MW of customer-owned solar photovoltaic capacity in the city.

Electric Vehicles. The State of California has set a goal of having 1.5 million zero emission vehicles on the roads by 2025. It is anticipated that the majority of these zero emission vehicles will be electric vehicles. As battery storage technology improves, the costs for electric vehicles will continue to decline, which will result in a higher participation in electrical vehicle ownership within the Utility’s territory.

• The City received a grant to have an electrical vehicle public charging station constructed in the McDonald’s parking lot, which is now completed, and running.

CITY OF BIGGS Biggs Municipal Utilities at a Glance

• Electric utility established in 1904 • Biggs is located in climate zone 11 • The electric utility has 736 retail customer connections servicing 698 retail customers • Percent of retail sales by customer class are as follows: residential, 43%, commercial, 7%

and industrial, 50% • Budgeted amount for energy efficiency programs for FY 15/16 was $9166.91 The

amount actually expended was $4668.11, funded through a 2.85% Public Benefits Surcharge. Unallocated funds were re-appropriated to augment funding for our Solar PV Incentive Program.

Utility Overview City of Biggs experienced a 9% load increase in FY 2016, reversing the trend of the last several years. Multiple factors contributed to the increase, including the addition of 20 single-family residential units and increased activity at our industrial customer, Sunwest Milling. Economic conditions in Biggs and the surrounding communities remain depressed, dampening customer enthusiasm for any investments in energy efficiency measures. Our customers who do have disposable income are choosing to invest in solar P.V. rather than energy efficiency measures. Of the 40 commercial properties we serve, 16 are empty and 9 are simply relay stations for cable, telephone service or rail road signals. An additional 4 are church properties used once or twice a week, so rebates for upgrades to their efficiency levels is not cost effective. Our summer cooling load is relatively high, due to our high summer temperatures and aging housing stock, but customers will not work with the city to replace aging systems unless rebate levels rise far beyond what is currently offered. We have yet to identify a cost effective way to make HVAC rebates available to our customers. Major Program Changes There have been no major changes in programs offered or budgeted funds for energy efficiency programs during this reporting cycle. With low customer participation, budgets were lowered and some unused funds were re-appropriated to support our Solar PV Program. Program Descriptions

• Referral to Community Action Agency for LiHEAP grants. • Commercial Lighting Program: Customized Lighting Retrofit Rebate Program available to

all commercial customers and educational facilities.

• Commercial HVAC Program : Customized HVAC Retrofit & Optimization Program provides generous incentives for businesses and educational facilities to update aging HVAC units or tune-up units that don’t need replacement.

• Residential Appliance Program: This program offers incentives to residential customers for the purchase of Energy-Star rated refrigerators and the recycling older units.

• Residential HVAC Program: Tiered incentives for replacement of aging HVAC units at residential properties. The greater the SEER level above Title 24 requirements, the greater the potential incentive. The Res. HVAC program also provides incentives for tune-ups of HVAC units, the installation of 7-day programmable thermostats and the installation of whole-house fans.

• Residential Shell Program: This program offers incentives for increasing insulation levels and installation of dual-pane, low E windows to replace existing single-pane. Future programs may include whole-house air sealing.

EM&V In 2007, in response to AB 2021, Biggs hired a third-party contractor to formulate an EM & V plan. In 2008, 2009 & 2010, Biggs contracted with Navigant Consulting to perform Energy Efficiency Program Evaluation studies of all programs the city offers. Those studies can be found on the NCPA website and our city website. With the understanding that all programs need not be evaluated every year, Biggs moved to evaluation of all programs, in three year blocks. Biggs is currently working to find a consultant to perform multiple years worth of EM&V reports and have budgeted $10,000 toward fulfilling our EM&V requirement. Sources of Energy Savings Data 2015 TRM and 2011 DEER were used to calculate savings. Complimentary Public Benefits Programs

• Renewable Energy Programs: Biggs offers incentives to customers who install up to 3 kW of solar PV capacity for residential service and custom incentive programs for commercial customers.

• Low-Income Programs: Biggs works with Community Action Agency of Butte County to provide weatherization, appliance replacement, lighting replacement and HEAP grants to income-qualified household within our service territory.

BURBANK WATER AND POWER Burbank Water and Power (BWP) At a Glance

• Located in Climate Zone 9 • More than 46,000 residential and more than 6,500 commercial electric service

connections, serving a total population of about 105,000 residents and more than 3,300 businesses.

• 1,086,100 MWh in total retail sales. Percent of retail sales by customer class – 26% residential, 74% non-residential.

• The Fiscal Year (FY) 2015-16 budget for energy efficiency (including EM&V, admin/overhead, incentives) was $3,507,400. Of this, $3,007,420 (86%) was spent. BWP’s funding source for energy efficiency programs is the Public Benefits Charge. BWP can reallocate unspent budgeted dollars to other Public Benefits programs or, more typically, invests them in the following fiscal year. In FY 2016-17, BWP has budgeted $3,618,000 for energy efficiency programs.

Burbank Water and Power Overview Burbank is known as the Media Capital of the World, and is home to two of the world’s largest studios, Warner Bros. and Disney. The city is also home to thousands of smaller businesses, many of whom moved to Burbank in the early 1990s after the aerospace industry contracted and real estate became plentiful and cheap. From BWP, these businesses have come to expect cost-effective and reliable electric service, as well as additional services such as fiber optic networking. At the same time, Burbank has a vibrant residential community, with a housing mix of about 18,500 single family homes that ranges from post-war bungalows to two story view homes. There are also about 27,000 multifamily homes, a figure that continues to increase with infill and high-density development. As a result of nearly 20 years of energy efficiency history, increasingly stringent codes and standards, and a community ethos of sustainability, the average Burbank household uses about 500 kWh per month. This efficient baseline makes it a challenge to design programs that can squeeze more energy efficiency juice out of an increasingly shrinking lemon. BWP’s energy efficiency portfolio has been designed to reflect our organizational goal of continuing to provide sustainable, affordable, and reliable service to all of our residents and businesses. At the same time, BWP is adjusting to changes in the utility industry, including concepts such as:

1. “Negative Load Growth,” where energy efficiency and subsidized distributed generation are “fully” offsetting economic growth; and,

2. The “Duck Curve”, where customer solar PV generation in the afternoon leads to a steep ramp up in the amount of electricity required to be supplied by the utility in the evening. This results in a daily load profile that resembles a duck, invalidating current Time Of Use (TOU) rate design and resource planning criteria.

To address the operational challenges of the Duck Curve, in FY 2014-15, BWP implemented a first-of-its kind policy to restrict solar PV rebates to systems that are westerly-facing. By orienting solar panels to the west, customers can increase their solar energy output during the afternoon peak hours while reducing output during the morning hours. The effect of these new initiatives,

along with an Electric Vehicle (EV) charger rebate and higher rebates for ENERGY STAR central air conditioners and variable speed pool pumps, to address these challenges are discussed in further detail below. Major Program Changes BWP has consistently led the way in innovation and quality especially during periods of industry change and transitions. FY 2015-16 has presented unique opportunities for the utility to grow and adapt to current events. On October 23, 2015, the Aliso Canyon Storage Facility north of Porter Ranch, CA suffered an unprecedented gas leak losing over 100,000 metric tons of methane gas in a four month period. Since 60 percent of the electricity used in Southern California is generated by natural gas and 17 power plants (including the Magnolia Power Plant operated by BWP and jointly owned with five other SCPPA members) are served by the Aliso facility, BWP had concerns that the leak might affect service in Burbank. In anticipation of potential shortages in service, BWP instituted a broad communications campaign to keep residents informed. BWP’s increased reliance on digital communications has resulted in increased engagement with, and more convenience for, customers. The following table shows the results of these efforts. In addition, BWP’s The Wire newsletter continues to offer business owners access to online energy efficiency tips, business cost savings, productivity increase advice and readily accessible information on “industry-specific utility” research topics in order to assist them to succeed while reducing energy expenditures.

Four key players are involved in HVAC supply—manufacturers, distributors, contractors, and commercial customers. Normally, commercial customers receive utility rebates for installing high-efficiency equipment, which is referred to as a “downstream” incentive. The “upstream” incentive works in reverse; whereby, incentives are given to distributors to stock and supply high-efficiency products for customers to install in their businesses. Industry research has shown that the “upstream” approach results in greater participation than its conventional incentive counterpart. BWP contracted with Energy Solutions, who is responsible for distributor outreach, collaboration, and incentive processing to provide above-code, high efficiency HVAC equipment, with incentives paid per ton based on the type of HVAC unit and the efficiency level. In FY 2015-16, the first year of implementation, the program achieved more than 300,000 annual kWh savings along with 160 kW peak demand annual savings that directly mitigates the impact of the Duck Curve. BWP provided rebates for more than 700 tons of cooling, while reducing the per unit cost by nearly 40 percent, and plans to expand the program in upcoming years. Also in FY 2015-16, BWP implemented EV Charger rebates in order to promote clean energy use and encourage residents to manage their electric load by charging their EVs at home and during off-peak hours. The new rebates are up to $500 for Level 2 chargers installed in residential homes and up to $1,000 for multi-family and commercial properties. In addition, residents who

receive the rebate are required to participate in TOU electric rates. TOU is an electric billing rate schedule designed to encourage customers to use electricity during the most cost-effective periods in the day. As a result of BWP’s complete Automated Meter Infrastructure (AMI), all commercial customers are already on TOU rates. In addition to addressing both negative load growth and the Duck Curve, BWP hopes that the rebates will encourage an increase in EV sales for customers, thus reducing harmful greenhouse gas emissions and helping to meet the state’s climate goals, and improving the environment for the Burbank community. Program Highlight For residents, BWP’s flagship program is the Home Improvement Program (HIP). Previously called the Green Home House Call (but later changed to better reflect what the program offered customers), HIP is available at no charge to participants. BWP introduced the program in November 2009 as a whole house, direct install program and has been expanding it ever since. The program was designed to reduce electric use and BWP has partnered with the Southern California Gas Company and the Metropolitan Water District of Southern California to leverage additional funding and reduce natural gas and water use as well. The program has several components, including an in-home audit with energy and water education and installation of CFL and LED lamps and water savings devices. In addition, BWP assesses single family homes for additional services including the installation of attic insulation, duct testing and sealing, central air conditioning tune-ups and air sealing, as well as outdoor water conservation measures. In FY 2015-16, the program served nearly 1,100 households, resulting in annual savings of nearly 700,000 kWh. With the current program, many of our participating residents are now qualified to receive incentives through the state’s Advanced Energy Upgrade California Program. Program Descriptions The following is a sampling of BWP’s largest programs by end-use: Residential Cooling and Non-Residential Cooling: BWP provides services that address all aspects of space cooling for residential homes and commercial buildings, including rebates for the purchase of high-efficiency air conditioners and heat pumps, and free HVAC tune-ups. For FY 2015-16, BWP increased the residential HVAC equipment rebate by $20 per ton, resulting in a 20 percent increase in participation. Residential Lighting: BWP provides free compact fluorescent and LED lamps to residents through our Home Improvement Program (HIP), as well as to participants in our Refrigerator Roundup program. In FY 2015-16, BWP provided residents with 2,000 LED lamps – 29% more lamps compared to the previous fiscal year. The use of LED lamps is another proven strategy for mitigating the effects of the Duck Curve. Residential Pool Pump: For FY 2015-16, BWP doubled the rebate for residential pool pumps from $200 to $400, resulting in an 85 percent increase in participation. Residential Refrigeration: BWP provides rebates for the purchase of ENERGY STAR refrigerators, including 230 in FY 2015-16. BWP also provides new ENERGY STAR refrigerators at no cost to income-qualified customers. In addition, BWP also removes and recycles residents’ second refrigerators at no cost in order to reduce their bills and lessen these older appliances’ impact on the grid. Through both of these replacement programs, 250 inefficient refrigerators were replaced with more efficient models generating nearly 130,000 kWh in annual electricity savings.

Non-Residential Lighting: BWP provides free direct installation services, including for high efficiency lighting, to all qualified small businesses in Burbank. In addition, BWP provides rebates per annual electricity saved for customized lighting projects, including $0.10 per kWh saved for LED lighting. Through these efforts, BWP generated 4.4 million kWh in annual electricity savings for our commercial customers. EM&V Along with most other POUs in California, BWP uses the E3 Reporting Tool to ensure accurate reporting of electricity and peak demand savings and cost-effectiveness. In order to verify these savings, and meet the requirements of AB 2021, BWP also builds evaluation, measurement, and verification elements into every program and facilitates independent third-party studies. BWP’s previous EM&V studies can be found at http://www.ncpa.com/current-issues/energy-efficiency-reports.html. Sources of Energy Savings The majority of energy savings values used to evaluate BWP’s program performance were obtained from the TRM developed for California’s POU by a third-party firm, ERS. In the case where an installed measure was not available in the TRM, BWP relied on vendor or other third-party data to estimate energy savings. Complementary Programs

• Low-Income Programs: BWP offers a Lifeline rate to about 2,000 income-qualified customers, a 40 percent discount off the standard residential electric rate, making it among the most generous programs in the state. BWP also offers the Refrigerator Exchange program for Lifeline customers.

• Renewable Energy Programs: BWP continues to offer its Solar Support Rebate program to both residential and commercial customers. In FY 2015-16, the rebate for residential customers was $0.64 per watt installed, and $0.49 per watt installed for commercial customers. During the current fiscal year, 28 rebates were provided for solar PV systems that are westerly-facing, in order to minimize the effects of the Duck Curve. Due to falling equipment prices, our Solar Support program continues to be very popular and has been fully subscribed. At the same time, 142 systems, or more than 80 percent of new residential solar photovoltaic (PV) systems were installed without a rebate, which demonstrates the increasing cost-effectiveness of solar PV systems.

• Research, Development, and Demonstration: BWP operates a demonstration program of 23 Ice Bear units installed at City-owned buildings and large businesses. The Ice Bear is a peak-shifting thermal energy storage unit that works with air conditioners. The unit is simply a tank containing water that is frozen during off-peak hours; the ice is then used to provide cooling, in substitution of the air conditioner’s compressor, during peak hours. In FY 2015-16, the units provided about 250 kW of peak demand capacity reduction, directly mitigating the impact of the Duck Curve.

• Energy Storage: In addition to the Ice Bear units, and investment opportunities at utility-

scale, BWP is investigating distribution-level and customer-owned energy storage in a number of ways, through Requests for Information and Proposals through SCPPA’s Energy Storage Working Group.

CITY COLTON ELECTRIC DEPARTMENT Colton Electric Utility at a Glance

• Colton Electric Department (CED) was established in 1895 by the City of Colton. • CED is in Climate Zone 10. • CED has 18,032 retail customer connections. 16,138 Residential, 2,033 Commercial, 76

Industrial, and 210 Municipal. • Percent of retail sales by customer class – Residential-28%, Commercial-19%, Industrial-

51%, and other 2%. • CED budgeted amount for energy efficiency programs was $1,244,000. The amount

actually expended was $813,912.75. All unused EE dollars are reallocated to other Public Benefits programs the following fiscal year.

Colton Electric Utility Overview Fiscal year 2015/2016 expenditures increased 109% ($388,744.31 to $813,912.75) from the previous reporting year. To help increase the number of participants CED expanded its selection of rebates and increased the direct installation budgets for commercial energy efficiency projects. Major Program Changes CED continues to expand its program development by entering into additional Southern California Public Power Authority (SCPPA) contract agreements to provide more EE programs for residential and commercial customers. This reporting year CED entered into an agreement with Southern California Gas Company to provide a joint low income direct installation program for manufactured homes in CED service territory. CED has also been able to increase its residential participation with additional rebate programs that support the water/energy nexus during this time of drought. Program Highlight The small business direct installation program made the greatest impact in terms of energy savings. The program provided 359,251 kWh’s of EE savings. These savings were a result of replacing T12 fluorescents to LED lights. 37 small businesses in Colton participated in the program and were satisfied with the decrease in their bill. The program that continues to provide the greatest community impact and support is the Living Wise school program. This program provided Energy and Water Efficiency kits for all 6th grade students and curriculum to the teachers in the service territory of the CED. This was the first funded educational outreach program to students from CED that provides a water energy nexus. The positive feedback from the teachers and students has made this program part of the ongoing growing portfolio of EE for CED.

Program Descriptions • EE Rebates Non-Res: Commercial and industrial customers participated in lighting and

equipment upgrades offering $0.075 per kWh saved on the projected first year’s savings.

• EE Rebates Res: Residential customers participated in varying energy efficient upgrades installed in their homes such as A/C upgrade rebates. Rebates all have different refund amounts depending on measure installed.

• Refrigerator Replacement Program (ARCA): CED assisted customers with replacing old inefficient refrigerator with new energy efficient models. The utility provided the new unit for $15 a month, billed for 12 consecutive months on the customer’s account. Total unit cost to the customer is $180.

• A/C Tune-Up: CED Changed this program to a rebate program from • KYC: Keep Your Cool was a new program offered to small commercial businesses with

inefficient refrigeration, lighting and cooling. The program provided $5,000 per location in EE upgrades.

• RHA Res: Residential customers with annual energy usage of over 10,000 kWh or previously participated in an energy audit received direct install EE measures.

• Synergy Non-Res: Small business customers with peak demands less than 20 kW participated in an energy audit and direct install of EE measures.

• Hospitality: Commercial program for lodging/hotels that provides a whole building approach for energy efficiency. EE measures included in this program are: retrofits for lighting to LED’s, insulation, HVAC controls, duct test and seal and pool and spa pump upgrades

• Living Wise Program: School based energy efficiency education program, designed to generate long term resource savings by bringing interactive take home kits containing high efficiency measures they use to install within their home.

EM&V CED contracted with AESC in this reporting year to complete a study of the residential direct install program and associated savings. The AESC study is available on CED website, (www.ci.colton.ca.us/DocumentCenter/View/3225). CED will continue to make EM&V reports available to the CEC and other parties as they are completed and will continue with its EM&V programs and practices in the future. Sources of Energy Savings The sources used to calculate program performance were the Technical Reference Manual (TRM) and Database for Energy Efficiency Resources (DEER).. The TRM was utilized for all measures that had not been updated in the 2014 Title 24 code changes. Complimentary Programs

• Renewable Energy Programs: This reporting year Public Benefit Funds did not fund any renewable energy programs. The Electric Utility enterprise fund, funded solar photovoltaic

rebates for residential customers and funded the planning and construction of a community solar project expected to be completed end of FY2015/2016.

• Low-Income Programs: Low Income applicants were provided a monthly credit of 139 kWh added to tier 1 at lower the lower .08 rate. This program change was the result of a program evaluation completed the previous reporting year.

• Research, Development, and Demonstration (RD&D): This reporting year CED is partnered with SCPPA to take part in a solar heat pump application on a water well location to cool down the city’s Water Department pumping station. This will be a joint study shared with other SCPPA utilities.

• Electric Vehicles: This reporting year CED was awarded grant funding from the South Coast Air Quality Management District to install three Electric vehicle charging stations curbside at two multifamily housing complexes. The installation is expected to be completed the end of 2016. Two additional chargers are also being planned to be installed to provide additional City departments EV charging.

• Energy Storage: Colton Electric Utility participated in an energy storage working group through SCPPA. Energy storage is not cost effective for the Utility at this time.

Utility Overview With the installation of digital meters, Glendale Water & Power (GWP) has developed new innovative energy efficiency, load management, and demand response programs for its customers. Our customers are eager to take advantage of the many benefits and new programs a modernized utility offers. Trends in utilities are leading towards digital communications, need for real time and near real time usage information that will help consumers take charge of their energy use and give them the tools to manage it. A modernized electric grid greatly expands data acquisition and data sharing across business units, lowers system losses, prevents energy theft and dramatically improves outage and asset management, reducing maintenance and capital costs with the goal of keeping downward pressure on consumer prices. For the current FY 2015-16 reporting year, GWP‘s energy efficiency programs saved 17,602 MWh (1.61% of retail sales) and reduced peak demand by 10.52 MW (3.17% of peak demand). With a modernized utility system, GWP will offer more programs and increase customer engagement through mobile applications to enable our customers to be stewards in conservation by giving them the tools to empower them. Major Program Changes In FY 2015-2016 we continued the implementation of two pilot programs. The Behavioral Demand Response pilot program which greatly contributed with peak demand reduction and the Conservation Voltage Reduction pilot program which was expanded and yielded an increase on energy savings. Program Highlights Our Home Energy Reports from OPOWER, the Large Business Energy Solutions program and the Conservation Voltage Reduction pilot program produced the most energy savings from our portfolio. The Home Energy Reports had the greatest impact on our residential customers, we are currently among the top reporting energy efficiency utilities from OPOWER’s portfolio. This program also reached the majority of our customers and provides constant communication and engagement. Our Business Energy Solutions program is a CMUA award winning program that is designed to allow GWP large business customers the flexibility to define their own needs and

develop their own energy efficiency projects. The Conservation Voltage Reduction pilot program was expanded to include two additional transformers which contributed to our increased annual energy savings. Program Descriptions Glendale Water & Power is a leader in many aspects of the utility industry. Along with aggressive conservation efforts, GWP has been giving back to the Community through its Public Benefit Programs. These programs not only assist low-income customers with their electric bills, they also provide funding and education for all customers to invest in new technologies helping them save money and lower their energy and water consumption.

• Healdsburg’s Electric Department was established in 1899. • Healdsburg is located in Climate Zone 2. • Healdsburg serves roughly 4,800 residential customers, 1,000 commercial services, and

50 industrial services. • Percent of retail kilowatt-hour sales by customer class are 34% residential, 55%

commercial, and 11% industrial. • Fiscal Year 2016-budgeted amount for Energy Efficiency Rebates was $156,000, actual

rebates paid in FY2016 was $115,000. Unspent moneys are allocated to low income discounts.

• Average load growth in Healdsburg is less than 1%. Healdsburg Electric Department Overview Healdsburg’s Electric Department manages a comprehensive energy efficiency program for residential and commercial customers focusing on energy conservation as well as peak load reduction. For residential customers, rebates incentivize the installation of a variety of energy efficiency measures. For commercial customers, rebates are available for upgrading lighting, refrigeration, HVAC, and custom programs where detailed analysis shows a benefit to cost ratio consistent with the Electric Department’s existing programs. Major Program Changes The City of Healdsburg continues to focus on refining residential and commercial programs to offer the best programs and services to our customers. In 2016, the City participated in an upstream LED rebate program offering two styles of LED bulbs at a discounted price for customers to purchase from three local retailers. In addition, the City hosted a Smart Living Healdsburg fair to the public offering information about energy and water efficiency, local programs, renewable energy, financing options, and featuring local vendors and organizations. The fair was small but successful, and will be hosted again in 2017 with a focus on growing attendance and offerings. Looking forward to 2017, the City will focus on restructuring and revitalizing our program offerings. Analysis will be done to identify new programs that offer benefit to our customers. Several programs have already been identified and are in the process of design and implementation:

• Direct install program for low income customers: this program will include a snapshot audit of the home, plus installation of up to nine energy and water saving devices.

• LED instant rebate pilot program: this program will offer an instant rebate at the point of sale for a variety of LED bulbs. Depending on the success of the pilot, the program could be expanded.

• Green business program: In partnership with the County of Sonoma’s Energy Independence program, the City will offer a green business certification to commercial customers. This program will offer services and assistance identifying and making energy efficiency improvements.

Program Highlight The City’s commercial energy efficiency program continues to be our most successful program. Calendar year 2016 saw rebates for new and different technologies, primarily in the wine processing industry. The City will continue to focus on developing commercial projects, especially with our wine industry customers, as there are large potentials for energy efficiency projects in these applications. The City of Healdsburg’s commercial energy efficiency program is completely customizable, based on the customer’s need and proposed project, and offers an incentive per kilowatt-hour as well as an adder (“kicker”) for peak demand reduction. The incentive for demand reduction provides higher value to projects that reduce system peak demands. This, as well as the residential programs, led to 986,602 kWh saved; roughly 1% of Healdsburg annual sales. Program Descriptions The City offers the following residential programs: • Energy Efficiency Hotline: The City’s electrical customers can call the City’s Utility Conservation

Analyst to answer questions and provide information on energy efficiency related matters.

• Free Home Audits: On-site energy and water audits are available to residential customers. Energy efficiency measures are recommended based on each audit and upon request, the customer is provided a written report summarizing findings and recommendations to reduce the customer’s monthly energy consumption.

• Appliance Rebates: The City provides rebates for the purchase of several ENERGY STAR® rated appliances.

• Residential Heat Pump and Efficient Air Conditioning Rebates: The City offers rebates for residential and small business customers who install high performance heat pumps, central air-conditioners or evaporative coolers that exceed current state requirements.

• Residential Lighting Rebates: The City offers rebates to homeowners who install ENERGY STAR® qualified LED lamps and LED string lights.

• Residential Electric Water Heater: The City offers customers a rebate toward the installation of new, energy efficient electric water heaters.

• Weatherization/Window Incentives: The City provides financial incentives for homeowners who invest in home weatherization and window replacement projects.

The City offers the following commercial programs: • Energy Audits and Rebates: This program offers complementary, on-site energy audits for

both commercial and industrial customers. Energy efficiency recommendations and follow up visits support implementation of recommended energy efficiency measures. Energy efficiency rebates are available for upgrades identified through these audits.

• Commercial Lighting: This program engages local lighting and electrical contractors to promote and install energy efficient lighting upgrades through technical assistance and financial incentives available from Healdsburg’s Electric Department.

• Commercial Refrigeration and HVAC: The City offers commercial customers a wide selection of refrigeration and HVAC rebates. These rebates are performance based and provided greater reward to projects that reduce system peak demand.

• Custom Energy Efficiency Programs: The Healdsburg Electric Department will consider custom energy efficiency programs for site-specific consumption. The Electric Department will require that the City’s contractor review and endorse all custom programs. This review may result in a small cost adder to the proposed project but validates the benefit to cost ratio of the program. The Healdsburg Electric Department retains the sole right to approve or deny custom projects.

EM&V Past EM&V reports can be found through the following link: http://www.ncpa.com/current-issues/energy-efficiency-reports.html. The City plans to complete additional EM&V reports in calendar year 2017. Sources of Energy Savings The City of Healdsburg relies on TRM data to calculate energy savings. Complimentary Programs

• Renewable Energy Programs: Although the City of Healdsburg reached its Net Energy Metering (NEM) installed capacity goal in January 2016, the City’s NEM program continues as designed, minus the rebate, for all customers interesting in pursuing solar installations. As a lower cost alternative, the City provides a “Green Rate” for customers choosing to fully cover their energy use from non-carbon sources.

• Low-Income Programs: The City of Healdsburg actively supports a low-income discount for low-income customers. Annually, this discount supports over 410 customers, or about 8.5% of the City’s residential customers.



• Research, Development, and Demonstration: In 2016, the City of Healdsburg worked to implement energy savings rebates and programs for vineyard and winery customers to help achieve large reduction in energy usage and demand. The City will continue to work on development and further implementation of this program.

• Electric Vehicles: The City of Healdsburg has one plug-in hybrid in its fleet and includes analysis of plug-in hybrid and eV alternatives when considering new fleet purchases. In addition, the City continues to provide and maintain six charging stations located at City Hall. These stations, four installed in 2015 and two in 2013, have supplied 89 MWh of energy and saved more than 37 metric tons of GHG. The City plans to install 12 new electric vehicle charging stations in 2017 as well as continue to grow our electric vehicle fleet.

• Energy Storage: The City of Healdsburg has not pursued energy storage projects as they continue to be cost prohibitive. Instead, the City incentivizes energy efficiency programs to promote the reduction of peak demand which has effectively limited the City’s historical growth in peak demand. The City does include energy storage as a consideration for new projects and, at such time that energy storage technologies become less expensive, our incentive programs no longer effectively reduce peak demand, or additional capacity is no longer available or cost effective to purchase, the City will pursue energy storage projects.

Imperial Irrigation District Overview As the third largest power provider in California, Imperial Irrigation District utilizes more than 1,200 megawatts of energy derived from a diverse resource portfolio that includes its own generation, and long- and short-term power purchases. IID’s Energy Department provides electric power to more than 149,000 customers in the Imperial Valley and parts of Riverside and San Diego counties. As a consumer-owned utility, IID works to provide reliable, efficient and affordably priced energy services to meet customers’ demands. The district’s diverse resource portfolio provides their customers with some of the lowest rates in Southern California, which is critical given the unemployment rates within the service territory continue to be among the highest in the nation. IID’s energy efficiency programs are a key factor in the utility’s overall goal of maintaining system reliability for the sustained benefit of the regional economy, the environment and the communities it serves. These programs provide a positive impact on utility costs by stabilizing energy consumption and reducing purchases of expensive peak power. Additionally, customers are provided with an opportunity to take charge of their energy utilization and by doing so, reducing their electricity consumption and cost. Major Program Changes The program portfolio and rebate levels remained consistent from previous years. Program Highlight IID’s Quality A/C Tune-Up Program, which offers refrigerant charge adjustment and duct test and seal measures at no cost for residential and small commercial account customers lead the path in popularity amongst participants. In 2016, over 3,500 customers participated in the program. Living in climate zone 15, routine HVAC maintenance is a necessity for IID customers. Not only

does the program offer the service at no cost to the customer, the cost per kilowatt hour saved is amongst the lowest in IID’s portfolio. Program Descriptions Commercial Customer Programs

• Commercial Audits: This program provides commercial customers with onsite energy evaluations of their facilities and helps the business owner identify opportunities for energy conservation. This service is offered at no cost to the customer and is recommended as the first step towards their energy conservation journey.

• Custom Energy Solutions Program (CESP): This program is designed to promote energy efficiency by offering financial incentives to commercial customers who install energy-efficiency equipment. The larger commercial customers that participate generally have their own energy efficiency specialists they’ve consulted with for their upgrades and have identified the details of their project prior to applying for the rebate. However, for all other commercial customers that may not have access to an energy efficiency specialist, IID offers technical expertise to assist them in identifying the energy efficiency measures and cost saving opportunities. Measures incentivized include interior and exterior lighting, process loads and HVAC/refrigeration.

• New Construction Energy Efficiency Program (NCEEP): This program combines an integrated design process with financial incentives for energy saving design at least 10 percent above the current Title 24 requirements for a building envelope; or as a systems approach method for individual measures.

• Energy Rewards Rebate Program: This program offers commercial customers prescriptive rebates for qualified energy efficient measures. Qualifying measures must retrofit, replace or upgrade old equipment with new, energy-efficient technologies that meet and/or exceed the Title 24 standards in effect at the time of installation.

• Quality A/C Tune-Up Program: Through this program participating small commercial account customers receive HVAC services which may include duct test and seal (DTS), refrigerant charge adjustment (RCA), inspection of all electrical connections and tightening, inspection of all moving parts and lubrication, inspection of condensate drain, inspection of system controls and thermostat setting, and cleaning of evaporator and condenser air conditioning coils.

Residential Customer Programs:

• Energy Rewards Rebate Program: This program offers residential customers prescriptive rebates for qualified energy efficient measures. Qualifying residential measures must retrofit, replace or upgrade old equipment with new, energy-efficient technologies that meet and/or exceed the Title 24 standards in effect at the time of installation.

• Quality A/C Tune-Up Program: Through this program participating residential account customers receive HVAC services which may include duct test and seal (DTS), refrigerant charge adjustment (RCA), inspection of all electrical connections and tightening, inspection of all moving parts and lubrication, inspection of condensate drain, inspection of system

controls and thermostat setting, and cleaning of evaporator and condenser air conditioning coils.

• Residential Audits: Customers may receive a free home energy assessment once every three years. An assessment will identify problems that may, when corrected, save the customer a significant amount of money over time.

• Refrigerator Recycling: This program is designed to encourage customers to recycle their old refrigerators rather than using them as a secondary refrigerator usually located either in uninsulated garages or outdoors. Through the program a customer’s refrigerator will be picked-up and recycled, in addition to them receiving a $50 incentive per unit.

Codes and Standards Beginning in 2016, through IID’s participation with SCPPA, IID will account for codes and standards savings, which are drawn from the statewide allocation of energy savings credits attributed to codes and standards. The codes and standards savings claimed by IID are pro-rated based on the district’s percent share of statewide load. EM&V IID completes quality assurance on all programs which includes pre and post inspections on a sampling of projects. The district also contracts with an independent third party to complete an Evaluation Measurement & Verification (EM&V) of a sampling of energy efficiency programs. Programs evaluated vary each cycle. IID budgets an average of $70,000 for the external EM&V. IID is scheduled to perform an evaluation of the 2015 and 2016 programs within the next calendar year. The results will be submitted to SCPPA and incorporated in the SB1037 report accordingly. Copies of IID’s past EM&V reports are available at http://www.ncpa.com/policy/reports/emv/. Sources of Energy Savings IID utilized a combination of savings from the TRM, KEMA 2009 report, utility work papers and custom savings when applicable. For the prescriptive rebate program, the district relied on the deemed savings provided by the TRM as the individual efficiency measure’s performance characteristics and use conditions were well known and consistent. Subsequently for the custom programs, custom savings were calculated taking into account the properties of existing equipment, replacement equipment and future use. Complimentary Programs

• Low-Income Programs As a large number of IID’s residential customers participate in its income-qualified programs, a significant portion of revenue generated through the public benefits charge is allocated towards these programs. Program expenditures for the 2016 year totaled over $6.3M, with an average enrollment of 13,900 customers.


o Residential Energy Assistance Program (REAP) – This program provides customers with a discounted rate on their electric bill. Qualification is based on the number of residents per household and the total gross income of all the income sources in the home. Qualifying customers may receive a 20 percent discount on their monthly bill. Qualifying seniors 60 or older may apply to receive a 30 percent discount.

o Emergency Energy Assistance Program (EEAP) – This program provides financial assistance to customers in a financial crisis, facing disconnection for nonpayment.

o Medical Equipment Energy Assistance Program (MEEUAP) – This is an assistance program that reduces the electric rate for a defined quantity of electricity used to operate medical equipment by a household that has a full-time resident who requires specific medically necessary electric equipment to sustain life or prevent deterioration of a person’s medical condition.

• Energy Storage: The District’s first ever battery energy storage system went online in November 2016. The project is a 30-megawatt, 20-megawatt-hour lithium-ion battery storage system that will increase reliability across the IID grid by providing the ability to balance power and integrate solar while providing spinning reserve and black start power restoration capabilities. IID anticipates its customers will benefit from reduced operating costs throughout the lifetime of the project, providing a significant cost savings to ratepayers. The project is one of the largest of its kind in the western United States.

• Renewable Energy Programs: o SB1 Solar Solutions Program – IID offers incentives to customers who install solar

systems. Two types of incentives are offered: Expected Performance Based Incentive (EPBI) and Performance Based Incentive (PBI). The EPBI incentive is a one-time payment based on verified solar energy system characteristics such as location, system size, shading and orientation. The PBI incentive is a flat cents-per-kWh paid annually, for all verified output from a solar energy system over its initial five-year operation. The program sunset in 2016.

o Net Energy Metering – IID pays net-surplus customers for excess generation electricity produced by eligible solar or wind power systems. Customers can also elect to receive a kilowatt credit rather than monetary compensation at rates established by the utility. This program sunset in 2016 as it achieved its state mandated MW cap.

o Net Billing – The Net Billing Program is NEMs successor program and also compensates net-surplus customers in accordance with the Distributive Self-Generation Service Rate.

LODI ELECTRIC UTILITY Lodi Electric Utility At a Glance

• Climate Zone 12 • Number of retail customer connections 26,012 • Residential Customer sales: 151,137,940 kWh (34%) • Commercial Customer sales: 161,089,550 kWh (37%) • Industrial Customer sales: 125,018,845 kWh (29%) • Budgeted amount for Energy Efficiency programs: $868,440 • Energy Efficiency Program Expenditures: $848,774

Lodi Electric Utility Overview Lodi’s non-residential customers (commercial and industrial) continue to produce the majority of energy savings achieved in Lodi Electric Utility’s (LEU’s) energy efficiency program portfolio. For the FY16, non-residential lighting upgrades and custom projects accounted for 84% of the acquired energy savings. Due to the age of Lodi’s housing stock, residential customers continue to achieve the greatest energy savings through HVAC replacements, improvements to insulation and by purchasing ENERGY STAR ® certified appliances, including refrigerators, dishwashers, clothes washers and pool pumps. The greatest opportunity for residential energy efficiency savings continues to be with low-income and rental property. Lodi’s median household income is estimated at $49,844 and renter occupied property comprises approximately 45 percent of all Lodi housing units. Program Highlights The Residential Direct Install and Snapshot Audit program offered installation of LEDs, advanced power strips, thermostatic shower valves, shower heads, and aerators in customers’ homes at no cost. The intent was to provide a program for residential customers that do not traditionally participate in energy efficiency rebate programs. While open to all residential customers, the program specifically targeted multi-family and low-income properties, as they are not likely to benefit from traditional energy efficiency programming, as well as serving single family homes. The Keep Your Cool Commercial Refrigeration program provided upgrades to commercial refrigeration equipment at no cost to LEU customers. The program included a variety of measures such as motors, motor controls, LED case lighting, anti-sweat heater controls, strip curtains, door gaskets and closers. The Non-Residential Rebate Program continues to be the main driver in regards to overall energy savings achieved. Through key accounts management, the utility maintains a proactive and positive relationship with Lodi’s largest energy consumers. These relationships are vital to Lodi’s overall economic development strategy and through them our large commercial and industrial

customers have been effectively encouraged to engage and make investments in lighting retrofits, process equipment improvements, behavioral modification, etc. Program Descriptions LEU manages a comprehensive energy efficiency incentive program for residential and commercial customers focusing on energy efficiency and peak load reduction. For residential customers, rebates are offered for the installation of various energy efficiency measures, such as lighting, HVAC, appliances, and weatherization. For commercial customers, rebates are available for upgraded lighting, HVAC, appliances, refrigeration equipment, electronics, and in cases where an analysis is performed rebates can be offered for additional equipment that reduces energy use and/or demand. On-site energy audits are provided by LEU energy specialists. Energy efficiency measures are recommended and additional visits are completed upon request.

• Residential Lighting [Res Lighting]: LEU offers rebates to homeowners who install ENERGY STAR qualified LED lamps/bulbs, ceiling fans and LED holiday lights.

• Residential HVAC [Res Cooling]: LEU offers rebates to homeowners who install high performance heat pumps and air-conditioners, or evaporative coolers that exceed current state requirements. LEU also offers a rebate for duct sealing when not required by code.

• Residential Equipment [Res Clothes Washers; Res Dishwashers; Res Pool Pump; Res Refrigeration; Res Electronics]: LEU offers rebates to homeowners who purchase new ENERGY STAR qualified products, including clothes washers, dishwashers, pool pumps, refrigerators and advanced power strips.

• Residential Weatherization [Res Shell]: LEU offers rebates to homeowners who invest in weatherizing their homes, including attic and wall insulation, window treatments, solar attic fans, and air sealing.

• Residential Water Heater Rebate [Res Water Heating]: LEU offers rebates to homeowners who purchase a new, energy efficient electric water heater.

• Residential Direct Install [Res Electronics; Res Lighting]: Audits are performed on residential homes and advanced smart power strips, faucet aerators, thermostatic shower valves, and ENERGY STAR rated LEDs are installed at no cost to the homeowner.

• Commercial Lighting [Non-Res Lighting]: LEU offers rebates to business owners who invest in the installation of energy efficiency lighting upgrades. There is a prevalence of inefficient lighting throughout the city instead of more efficiency fluorescent or LED fixtures.

• Commercial Custom [Non-Res Comprehensive]: LEU offers rebates to business owners based on site-specific consumption. Rebates are tailored to the individual business owner’s needs based on the audit and the potential energy savings associated with the customer project.

EM&V LEU has implemented an Evaluation, Measurement & Verification (EM&V) Plan, and has completed eight consecutive annual assessments (reports) of randomly selected programs and large rebates

as part of the designed EM&V Plan. Our EM&V reports are available for review at: www.ncpa.com/policy/reports/emv/ Note: The annual assessment for FY16 is expected to be completed by June 30, 2017. Sources of Energy Savings For FY16, LEU has relied heavily on the savings listed in the Technical Resource Manual. The Commercial Lighting and Commercial Custom programs use custom savings calculations. Complimentary Programs

• Low-Income Programs: o Lodi C.A.R.E. Package Program: Provides grants to very low-income customers in

need of assistance paying their electric utility account; the program coordination/customer screening is performed by the Lodi Salvation Army.

o Lodi SHARE Discount Rate: LEU provides a rate discount of 30% for qualifying residential customers on their electric utility monthly billing statement; $400,000 annually is budgeted for this rate discount from the Lodi Public Benefits Program fund.

• Renewable Energy Programs: Since 2008 LEU has offered solar rebates to residential and non-residential customers. FY17 will be the final year of the incentive program.

• Research, Development, and Demonstration: LEU evaluated a thermal energy storage solution as a potential pilot project for Research, Development and Demonstration purposes. The project was to be a component of a larger public improvement project for the Lodi Public Library and would have augmented the existing air conditioning system by storing energy in the form of ice during off-peak hours and subsequently releasing the stored energy to cool the building, thereby reducing typical peak cooling loads. Unfortunately, implementation of the evaluated Ice Bear energy storage system was determined to be a financially infeasible solution for the project after the Library’s mechanical engineers completed their evaluation of the existing air conditioning systems and compared the costs of traditional improvement measures with the estimated the costs of implementing the ice bear energy storage system.

• Electric Vehicles: LEU is a proud partner with the California Municipal Utilities Association, the California Center for Sustainable Energy and the Clean Vehicle Rebate Project in the promotion of PEVs in our community and in California. LEU continues to provide a total of seven free Level 2 charging stations at five municipal parking facilities. LEU also offers customers a discounted EV charging rate.

• Energy Storage: LEU is participating in the NCPA/SCPPA joint contract with DNV GL to provide an updated evaluation of energy storage technologies.

• Educational Outreach: Lodi LivingWise Program: Provided curriculum to 16 teachers and home energy efficiency “kits” and manuals to 430 6th grade students in Lodi schools; the program is designed to teach the students the basics of energy and water conservation and allows them to install and experience energy efficient devices within their own homes.

CITY OF LOMPOC City of Lompoc Electric at a Glance

• Established in 1923 • Climate Zone 5 • 15,060 retail customer connections – 88% residential; 11% commercial, 1%

municipal/street lights • Retail sales by customer class – Residential - 55,691,428 kWh; Commercial - 66,121,906

kWh; Municipal 11,943,080 kWh; Street Lights and Traffic - 1,066,424 kWh • The budgeted amount for energy efficiency programs for FY15 -16 was $177,000. The

amount expended was $86,222. Any collected fees not expended are restricted and carried over to succeeding years.

Utility Overview Energy efficiency program participation remains flat over recent years due to a combination of trends in the local community such as the climate, continued drought conditions, demographics and market saturation. The City of Lompoc is located in the Central Coast region which provides a mild Mediterranean climate year round. Due to the mild climate, air conditioning is not typically installed in residential buildings and is limited in commercial buildings. Heating is done primarily with gas. The average residential electric consumption per month is 325 kWh. The peak demand for electricity is in the winter in the early evening. Since there is little need for air conditioning in our coastal climate and heating is primarily done with gas, the majority of rebate programs are focused on lighting and refrigeration retrofits. The Commercial Lighting program continued to have less participation than in previous years due to market saturation and the impact of building code requirements and Title 24 Building Energy Efficiency Standards requirements. The increased codes and standards requirements have discouraged many of the small commercial customers with limited funds from participating. Due to the continued drought and a fourth year of water and sewer rate increases, conservation staff assisted more customers with water conservation programs than with energy efficiency programs. Customers are choosing to spend available funds on retrofits that will help them save water. The City of Lompoc also provides water service to its customer and provides a variety of water conservation incentive programs. Programs offered include clothes washer and dishwasher replacements, toilet retrofits, rain barrel and landscape conversions. Because water conservation programs are not funded by Public Goods charges, energy savings are not reported. Major Program Changes No major changes were made to energy efficiency programs in this reporting period. The City will continue to survey the needs of its customers to provide additional opportunities for energy

efficiency savings. In 2016, the City entered into a Support Services Program Agreement with NCPA. By entering into the agreement, the City hopes to be able to provide more energy efficiency programs to customers at greater economies of scales. Programs being considered are direct install programs for low income, multi-family and commercial customers as well as an LED lighting upstream rebate program. Program Highlight A parking lot LED lighting retrofit project at a community college contributed to a large percent of the savings reported. The college received money from a grant to help them with the costs. Because the majority of customers are residential customers, the most popular programs were Residential Energy Star and Low Income Energy Star Refrigerator Recycle programs. The low income program is popular due to a larger incentive. In order to encourage participation in residential energy efficiency programs, the City will continue to provide programs that heavily subsidize the initial purchase. Customer audits continue to be successful in meeting customers’ needs. An increased number of customers are taking advantage of free energy audits. Many customers are able to implement staff suggestions from the audits and reduce energy use without the need to spend money on energy efficiency upgrades. Program Descriptions Res Refrigeration:

• Energy Star Refrigerator and Freezer Recycle Program: This program provides a rebate to customers who purchase an Energy Star refrigerator or freezer and recycle their old appliance at the City of Lompoc landfill.

• Buy Back Refrigerator and Freezer Recycle Program: This program provides customers a rebate to dispose of their extra refrigerator or freezer and recycle it properly at the City of Lompoc landfill.

• Income Qualifying Energy Star Refrigerator & Recycle Program: In this program, the City purchases an Energy Star refrigerator to replace a customer’s working primary refrigerator from a participating dealer. The customer must participate in the Electric Rate Assistance Program and pay a portion of the cost back to the City over a year. Appliances must be recycled at the City of Lompoc landfill.

Res Lighting:

• LED Bulb Exchange Rebate Program: Rebates are available to exchange an incandescent bulb with an Energy Star LED bulb.

• LED Holiday Light Rebate Program: The City offers a rebate to purchase up to 5 LED light strands per year.

Non-Res Lighting:

EM&V All appliance, lighting and custom rebate programs require a staff member to perform inspections before and after the installation. An on-site energy audit is performed. All appliance and lighting rebates require a verification of disposal from the City of Lompoc landfill. Lompoc’s EM&V reports can be found at http://www.ncpa.com/policy/reports/emv/. Sources of Energy Savings The City of Lompoc generally relies on the TRM as the primary source for deemed energy savings used in the calculating and reporting of annual program performance. Complimentary Programs

• Low Income Programs: The City provides financial assistance to customers that are below low to moderate income levels (as determined by HUD). The assistance is paid toward their electric usage charge. These customers are eligible for the Income Qualifying Refrigerator Recycle program and Clothes Washer Replacement program (not funded by Public Goods Charges).

EETAP was designed to assist commercial, industrial, and institutional customers in closing the gap between project development and implementation for more complex building systems. By providing incentives for project development services including energy auditing and project management, through this program, LADWP aims to help its customers to strategically plan, follow through and realize energy savings in the most cost-effective manner. (Non-Res Comprehensive)

Cross Cutting Programs Descriptions • Codes, Standards & Ordinances (CSO): The Codes, Standards & Ordinances Program

conducts advocacy activities to improve building, appliance and water use efficiency regulations. These activities include monitoring and active participation in code and standard development, compliance and enforcement support with our sister agency LA Department of Building and Safety, legislative review, sponsorship of local ordinances, and participation in policy efforts with other City departments, state agencies, and utilities. The goal of this program is to promote sustainability with regard to water and energy use. The principal audience includes the LA City Department of Building and Safety, LA City Planning, LA City Department of Public Works, and the LA City Council, which together develop and adopt codes and standards specific to Los Angeles that go beyond state and federal regulation. Other audiences include state agencies, which conduct periodic rulemakings to update energy efficiency and water conservation regulations and standards, and industry groups that conduct research and develop industry specific standards. (Non-Res Process)

• Million Trees Program (MTP): The Million Trees Program provides free shade trees for residents and property owners in Los Angeles to promote the planting of trees to improve building energy efficiency. This is a joint program managed by Million Trees LA and supported by LADWP. Through this partnership, MTLA is able to provide free shade trees for residents and property owners in the City of Los Angeles along with information on where to plant the trees for maximum energy efficiency benefits. MTP currently focuses on providing trees for residential customers but will also provide trees to commercial customers. (Res Cooling, Res Shell)

• LADWP Facilities Upgrade: The LADWP Facilities Upgrade Program strives to improve energy and water efficiency throughout LADWP’s facilities with energy efficiency upgrades in HVAC and lighting and water efficiency upgrades in plumbing fixtures, leak correction and landscaping improvements. It identifies and assists those LADWP facilities to reduce energy and water usage, which will result in a reduction in energy and water consumption and procurement expense for LADWP that would otherwise be borne by LADWP customers. (Non-Residential Cooling)

• LADWP Emerging Technologies Program (ETP): The LADWP Emerging Technologies Program is designed to accelerate the introduction of innovative energy and water efficient technologies, applications, and analytical tools that are not yet widely adopted in California. By reducing both the performance uncertainties associated with new products, as well as institutional barriers, the ultimate goal of this Program is to increase the probability that promising energy and water efficiency technologies will be commercialized and adopted throughout Los Angeles.

• Program Outreach & Community Partnerships: The Program Outreach & Community Partnerships Program is an advocacy program that strives to improve customer awareness among “Hard-to-Reach” customers of LADWP on electric and natural gas energy efficiency and water conservation programs through community based outreach organizations. In FY 2013/14, this Program offers $45,000 grants to 17 local non-profit

organizations that are selected to work in each Los Angeles Council District or on an at-large basis to provide community/customer awareness of LADWP’s core energy efficiency and water conservation programs.

efficiency market impacts of all the combined efforts of City of Los Angeles (inclusive of LADWP’s efficiency programs). The final EM&V report includes the preliminary Market Transformation (MT) evaluation plan. One of the end results of the MT evaluation quantifies the incremental energy savings potential due to market intervention introduced by the City of Los Angeles and a plan to track market indicators to recalibrate early projections moving forward. Sources of Energy Savings Sources of energy savings include custom engineering calculations using industry standard modeling software such as EnergyPro and eQuest. LADWP’s Custom Program uses this approach. For direct install and residential programs, deemed savings supported by a combination of the latest Technical Reference Manual as well as utility workpapers are used. Examples of programs using this approach include the Consumer Rebate Program, the Food Service Program, Refrigerator Exchange and Refrigerator Recycling Programs. Complimentary Programs

• Low-Income Programs: Refrigerator Exchange Program and Home Energy Improvement Program (described above).

• Solar Incentive Program (SIP): The Solar Incentive Program offers incentives to offset the cost of installing a solar rooftop system on your home or business. LADWP has been helping our customers to go solar since 1999. In September 2007, the LADWP revised its earlier SIP guidelines to comply with Senate Bill 1 (SB 1), the California Solar Initiative. Under this legislation, the LADWP has committed to providing $313 million to support solar photovoltaic (PV) projects over 10 years—through 2016—with a goal of achieving 280 megawatts (MW) of solar PV by the end of that period.

• Green Power for a Green L.A. Program: The Green Power for a Green L.A. Program gives Los Angeles residents, businesses, and governmental agencies a stake in helping to preserve and protect our environment through their voluntary contribution to support additional renewable energy. Customers who sign up for Green Power choose to have all, or a portion, of their electricity needs generated from renewable energy sources.

• Research, Development, and Demonstration: o LADWP has promoted thermal energy storage (TES) technology since the

early1990s and paid incentives for the installation of TES. o In August 2016, LADWP issued a solicitation for a pilot test plant to evaluate the

performance of a 100 kW lithium-ion battery system and 100 kW flow battery. o In November 2016, after thorough testing and review, LADWP approved the

SolarMax FLEX Energy Storage System (lithium-ion battery) for installation by customers, which may be of particular interest to customers with solar PV arrays.

o LADWP is involved in energy storage studies and projects using various technologies and use cases, including lithium-ion, flow batteries, compressed air, thermal energy storage at levels of the power system, including generation, transmission, distribution, and behind the meter.

• Electric Vehicles Electric Vehicle Charger Rebate Program: LADWP introduced the Electric Vehicle Charger Rebate Program, “Charge Up L.A.!” to encourage the installation of convenient electric vehicle (EV) charging stations at residential and commercial locations to support the purchase and use of EVs. This program benefits the environment and helps EV users save on fuel costs at the same time. The rebate is offered to qualifying commercial customers who purchase and install Level 2 (240-volt) chargers at their place of business for employees and public use. Commercial customers can receive up to $4,000 for hardwired wall or pedestal mounted or EV chargers. One (1) EV charger rebate is available to commercial customers who have a minimum of three (3) parking spaces available to employees, customers, visitors, and/or tenants. One (1) additional EV charger rebate is available for each additional 10 parking spaces. Residential customers can receive a rebate of up to $500 toward their out-of-pocket expenses for an EV charger. The rebate does not cover the cost of installation. Customers who choose to install an optional dedicated time-of-use (TOU) meter will qualify for the LADWP’s EV discount of 2.5 cents per kilowatt-hour (kWh), plus receive an additional $250 bonus. This dedicated service will add additional cost to the installation process but will yield lower electricity costs for off peak charging.

MERCED IRRIGATION DISTRICT Utility Overview

• For more than 75 years, the Merced Irrigation District (MID) has been in the business of generating wholesale electrical power.

• Fourteen years ago, MID determined the best way to leverage its investment in low-cost generating facilities, and to benefit Eastern Merced County communities was to develop its own electric delivery system.

• In 1996, MID created the Electric Services Department, and Foster Farms in Livingston, CA became the District’s first electric customer.

• MID’s electric distribution system has continued to grow with the addition of a 34-mile transmission loop and a sophisticated distribution system supporting customers in Eastern Merced County.

• MID sells electricity generated at its New Exchequer hydro power plant to PG&E.

MID Energy Efficiency Program Highlights In 2000, MID-Electric Services created and implemented the Public Benefit Programs. These programs promote, assist and educate all electric customers to participate and install energy efficiency measures. Commercial Customer Programs

• Commercial/Industrial Lighting Program: The Commercial Lighting Program is a turnkey lighting retrofit rebate program with a financial rebate menu for energy saving lighting equipment retrofits. The menu includes generous rebates for the replacement of T-12 lamps, Metal Halide Fixtures, Incandescent Lighting, and Exit Signs. The program also provides rebates for the addition of lighting controls including Photocells and Occupancy Sensors.

• Commercial/Industrial Mechanical Equipment Program: The Commercial/Industrial Retrofit Program is a turnkey mechanical equipment rebate program with a financial rebate menu for energy saving mechanical equipment retrofits. The menu includes generous rebates for the replacement of mechanical equipment with more energy efficiency equipment including: Refrigeration Equipment, Air Conditioning Equipment, Chillers, Motors, and Pumps. The program also provides rebates for Variable Frequency Drives on pumps, motors, and fans. Rebates are also available for Cooling Load Reduction measures to include Duct Sealing, Cool Roofs, Window Film, and Programmable Thermostats.

• Customized Commercial/Industrial Retrofit Program: The Customized/Industrial Retrofit Program enables qualifying commercial and industrial customers to apply for financial incentives on more specialized and comprehensive energy saving measures that do not fall under the Commercial Lighting Program or the Mechanical Equipment Retrofit Program. Applications for this program are evaluated and approved on an individual per application basis. Financial incentives for qualifying customer projects are paid for annual kilowatt hour savings in a one year period on approved projects.

Residential Customer Programs

• Residential Rebate Program: This program encourages residential customers to purchase EnergyStar® labeled products, home appliances and energy-efficient compact fluorescent light bulbs.

• Residential Energy Assistance Program (CARE): Since 2000, MID has been providing a 20 percent discount on monthly energy bills for Low-Income Families, and the Medical Baseline and Life-Support Program for those who depend on electrically powered medical equipment.

Complimentary Program: • Solar Incentive Program: The Solar Incentive Program provides financial incentives to

qualifying customers to buy down installed solar generation projects and to help offset the customer’s investment in renewable energy generation. The rebate incentive is equal to the estimated performance of the installed solar system multiplied by $.50/wattAC. The rebate incentive for commercial/industrial solar systems are capped at $12,500 (25kW) and $1,500 (3kW) for residential.

MODESTO IRRIGATION DISTRICT Modesto Irrigation District (MID) At a Glance

• Climate Zone 12 (entire service area) • 121,000 active retail service connections/customers served (approx.) • Total retail electric sales by customer class are: 34% residential; 29% commercial; 32%

industrial; 4% agricultural and pumping; 1% other (based on 2016 GWH) • $5.6 million budgeted for Energy Efficiency (EE) programs (including EM&V, admin /

overhead, incentives) • $3.6 million actually expended for EE programs

MID Overview MID electric sales have remained essentially “flat” over the past decade. The last major increase in energy sales occurred in 2004 (+3%) and significant reductions occurred in the recession years of 2009 and 2010 (-3% and -4%, respectively). Regarding capacity, MID hit an all-time system peak in 2006 of 687 MW (controlled), whereas the peak for 2016 was only 662 MW (uncontrolled). Load growth for 2016 was +0.8% (based on Total System Input GWH). Clearly, the economy in the central valley continues to affect MID and its customers, which in turn impacts EE program participation and results. Another trend in the MID service area is a significant installation of leased solar systems, which require little or no out-of-pocket cost for the homeowner. The customer motivation for installing these systems includes high utility rates and the perceived certainty of reduced future electric bills. Installation of these systems has reduced system load growth and may also dampen residential customer interest in pursuing EE projects. Major Program Changes In 2016 MID introduced two new pilot programs. The first was a LED bill credit rebate for the purchase of qualified LED lamps for residential and small commercial customers. The second was a mobile home direct install energy efficiency program. Both programs were very popular with their target markets. Program Highlight The Mobile Home direct install energy efficiency pilot program was an attempt to better serve a demographic dominated predominately by senior low and fixed income customers. MID selected a contractor who was qualified to implement direct install energy measures in mobile homes and was also able to offer no-cost utility weatherization services for qualifying MID electric and PG&E gas customers. This “one-stop” approach to combine programs and utility services received excellent feedback from customers.

Program Descriptions MID offers incentive programs that cover a wide variety of energy efficiency measures. The common theme for these programs is for customers to be MPowered. The correlation between these program offerings and the Sector/Category classifications used in the summary table of the E3 reporting tool are shown below.

EM&V (Evaluation, Measurement & Verification) MID continued its ongoing efforts to obtain independent, third-party review of its EE programs. To that end, MID hired Power Services, Inc. (CMVP qualified) to perform M&V on selected 2016 projects - in conjunction with the rebate review and approval process - which included lighting, process, control systems, refrigeration and compressed air. In 2016, MID also collaborated with Turlock and Merced Irrigation Districts and jointly hired Navigant Consulting to conduct EM&V on 2014 and 2015 EE programs. That study will be concluded in 2017. Preliminary steps were also taken to hire Navigant Consulting in 2017 to conduct EM&V on the 2016 EE program. MID’s

annual budget for EM&V work is $75,000 and completed studies can be found at: http://www.ncpa.com/policy/reports/emv The independent studies have consistently found the Realization Rate for MID’s EE program portfolio to be within a few percentage points of 100%. Those results demonstrate that MID is accurately reporting the savings from its EE programs. The accuracy of reporting is due in part to the quality assurance practices MID staff applies on an ongoing basis throughout the review and approval cycle of applications for its EE programs. Sources of Energy Savings MID offers two types of rebates: express and performance, which are based on deemed and calculated savings, respectively. The deemed savings for the express rebates are based on a combination of TRM, KEMA, DEER and IOU work paper data. The calculated savings for the performance rebates are based on ex-anti and ex-post data from the specific project. Complimentary Programs

• Low-Income Programs MID’s low income programs are comprised of weatherization, CARE rate discount and educational outreach. Energy savings from the weatherization program are included in the results for the SB1037 report. Customer demand for weatherization exceeds the annual amount budgeted and the rate discount alone represents a substantial portion of the total public benefits funding allocation. However, MID continues to facilitate new partnerships with other organizations and agencies to increase its outreach and provide additional weatherization services to low-income customers.

• Renewable Energy Programs MID’s renewable energy programs are no longer funded from public benefits. Rather, they are conducted in accord with subsequent legislative or regulatory mandates, such as the Renewable Portfolio Standard (RPS) and the California Solar Initiative (CSI/SB1). To date, MID has procured enough renewable energy to satisfy the renewable energy trajectory that was established by the CEC for the three compliance periods through 2020, and is currently considering its options for meeting the newly established post-2020 targets.

• Energy Storage In 2014, the MID board of directors adopted a policy determining that energy storage targets are not appropriate for MID. However, MID continues to evaluate the energy storage benefits that are applicable to its system and will consider updating this policy if warranted by operational and/or economic needs.

industrial • FY15-16 total budget for energy efficiency programs: $1,000,000 • FY15-16 total amount actually expended for energy efficiency programs: $285,000

Moreno Valley Utility (MVU) Overview MVU continues to experience modest load growth attributed to the successful business attraction efforts of the City’s economic development group and an expanding local economy. MVU’s peak demand increased by nearly 20 percent from last year’s report of 39 megawatts to 46 megawatts. The peak occurred on June 20th, which was highly unusual because it was unseasonably early and it happened on a Monday. Although MVU has seen double-digit load growth in the last few years, this trend may be mitigated by high levels of solar penetration – specifically large systems proposed by commercial customers. Some of these same commercial customers are also planning large LED lighting retrofits which, if approved and installed, will further erode MVU’s retail sales. Major Program Changes With the addition of residential programs last year, MVU has seen a slight increase in customer program interest and submitted rebate applications. It is clear that effective marketing efforts will be required to drive higher participation levels and that will be the focus this fiscal year. Due to the newer already-efficient housing stock in MVU’s service territory, the utility will add Tier 2 plug load devices to the list of Direct Install measures to capture additional energy savings. MVU might also develop programs targeting low-income residents and possibly some educational outreach to local schools. Program Highlights For the last two consecutive years, MVU’s Lighting Retrofits Program has been the most successful energy efficiency program and yielded the highest reportable kilowatt hour savings. The lower price and greater performance of new LED lighting technologies make large T5 high-bay replacement projects attractive, often with simple paybacks of about three years. MVU created a Demand Response pilot program by providing Ecobee smart thermostats to a small group of interested residential and small commercial customers. The installation is free and the customers will be allowed to ‘opt-out’ of demand response events but ‘opt-out’ customers will not receive compensation in the form of a bill credit for participation in the event.

Program Descriptions MVU offers many rebate programs to residential and commercial/industrial customers, only descriptions of the most popular are listed:

• Lighting Retrofits – Non-Res Lighting: rebates are available to commercial customers for LED lighting retrofits, other energy efficient lighting replacements, and for LED or photo-luminescent exit signs.

• Commercial Energy Efficiency Program – Non-Res Comprehensive: this Direct Install program provides small to medium-sized customers with an onsite energy audit and energy saving measures at no cost to the customer.

• Commercial Heating, Ventilation and Air Conditioning (HVAC) Retrofits – Non-Res Cooling: customers that install new high SEER HVAC units or replace older inefficient units can participate in this rebate program. The installation of new chillers that exceed Title 24 requirements or load-shifting Thermal Energy Storage (TES) systems may also qualify for rebates.

• Motor Replacements – Non-Res Motors: commercial customers that install premium efficiency motors are eligible for rebates under this program. Motors covered under this program must be new, three-phase induction motors (1hp to 200hp in size) and operate for at least 2,000 hours per year.

• New Construction and Major Tenant Renovation – Non-Res Shell: this program offers incentives for projects exceeding Title 24 by at least ten percent. Eligible customers are responsible for providing documentation of energy savings using energy modeling software and all calculations must be signed by a licensed mechanical engineer.

• Outreach Programs – Non-Res Behavior: the utility contracts with Automated Energy to provide the largest commercial customers with detailed energy usage information to help efficiently manage their energy consumption and evaluate potential energy efficiency projects.

• Residential Energy Audit & Direct Install – Res Comprehensive: this program targets very high energy use customers and participants in our Low Income Program. The program provides eligible residential customers with a full in-home energy audit and specific recommendations for their home plus a fixed set of maintenance and upgrades at no cost to the customer.

• Energy Star Appliance Rebates – Res Clothes Washers/Dishwashers/Etc.: customers who purchase Energy Star Qualified appliances can apply for a fixed rebate amount under this program.

EM&V Engineering analysis programs such as DOE-2 are the basis for calculated energy savings and incentive calculations. MVU requires both pre-inspections and post-inspections for all projects that result in a commercial rebate over $5000. The utility uses a third-party consultant to verify energy savings for complex projects and custom measures when necessary. As energy efficiency programs evolve and participation levels increase MVU will contract with one of the SCPPA-preferred EM&V service providers to create a plan.

Sources of Energy Savings MVU relied primarily on the TRM values from the E3 model but also used reported energy savings from trusted engineering contractors to calculate program performance.

• Commercial Codes & Standards – MVU has recorded its share of the energy savings that are attributable to the State’s Building Codes and Appliance Standards (Title-24) that are applied and enforced by the City of Moreno Valley.


• Low-Income Programs: MVU’s Low-Income Assistance program provides qualified low-income residents with a 20% discount on monthly energy charges; this year’s expenditures were over $65,000.

• Renewable Energy Programs: The Solar Incentive Program has been extremely successful having expended over $1M to provide rebates for 200 solar projects during the last fiscal year. The results were over 3.6MW installed with an annual estimated production of more than 7.8 megawatt hours. MVU’s largest commercial customer solar installation was completed in July at a size of 2.5MW. The first MVU-owned solar project has been approved and is in the design phase. It will be an approximately 500kW solar carport located at City Hall.

• Research, Development, and Demonstration: with the assistance of a CEC grant, MVU installed its first utility-owned electric vehicle charging stations at a customer location, the Walmart parking lot. The chargers consist of one DCFC fast charger and four L2 chargers on the Greenlots network.

• Electric Vehicles: compliments of a SCAQMD grant, this year additional utility-owned charging stations will be added to City Hall for workplace and visitor charging. So far there has been little interest from MVU customers in electric vehicle and charging station installations or incentives.

• Energy Storage: battery storage will be included in the City Hall solar carport project. There have been a few proposals by commercial customers to include battery storage with new solar installations but none have actually been installed. To date, there have been no battery systems installed on MVU’s distribution grid.

CITY OF NEEDLES City of Needles at a Glance

• Needles Public Utilities Authority (NPUA) was established in 1982. • Needles has 2,840 meters, 2,418 residential customers, 485 commercial customers, 1

municipal customer and 4 master metered. • Total energy sales were 54,090,085 kilowatt-hours (FY2015-16); 46% is residential sales

and 54% is commercial (includes business, schools, parks ect..) • The City has entered into a contract (Contract No. 87-BCA-10098) with the United States

Department of Energy Western Area Power Administration (“WAPA”) to purchase Federal hydro power from the Parker-Davis generating facility. The contract with WAPA expires in 2019. Approximately 55% of the City’s current electric energy is purchased from WAPA.

• The Public Benefits program funds the Low-Income and the Solar Rebate programs for $200,000.00

Overview The City of Needles is a severely disadvantaged community. The average household income is $43,372. The EE program(s) not only assist the NPUA’s load factor, but assist the community residences with lower monthly utility bills. Major Program Changes The Low-Income program was expanded to include Energy Star Appliances, which will use 10 to 50 percent less energy than standard appliances. Program Highlight The Low-Income program reduces Needles’s peak load factor. High temperatures in the summer cause the peak load to be mostly air conditioning loads, which are lessened by the more efficient HVAC installations. Program Descriptions

• Low Income Energy Efficiency Program: Provides rebates to low-income customers for HVAC, ENERGYSTAR® appliances, and the sun shade program.

Sources of Energy Savings Needles relies on the TRM for energy savings estimates for its programs.

CITY OF PALO ALTO UTILITIES City of Palo Alto Utilities at a Glance

• Climate Zone(s): 4 • Number of retail customer connections: 29,500 electric retail customers • FY15-16 total retail sales by customer class

o Residential 19% o Commercial 59% o Industrial 22%

• FY15-16 total budget for electric efficiency programs (including EM&V, admin/overhead, incentives): $5.69 million

• FY15-16 total amount actually expended for electric efficiency programs: $2.43 million City of Palo Alto Utilities Overview CPAU has implemented a variety of energy efficiency programs since the 1970s. In 1998, in response to California’s landmark energy legislation (AB 1890), CPAU established the Electric Public Benefits (PB) Program and increased the Electric PB program budget to 2.85 percent of projected annual revenue to fund energy efficiency programs. CPAU’s electric efficiency program budget can be supplemented with supply funds in order to meet state requirements that publicly owned electric utilities, in procuring energy, shall first acquire all available energy efficiency and demand reduction resources that are cost effective, reliable, and feasible. CPAU is committed to supporting environmental sustainability through promoting efficiency programs, promoting distributed renewable generation, and influencing consumer demand through incentives and education. In March 2013, Palo Alto City Council approved a Carbon Neutral Electric Resource Plan committing CPAU to a carbon neutral electric portfolio beginning in 2013.

Major Program Changes FY 2016 was a year of transition for the efficiency programs at CPAU. Many EE programs were updated or initiated, which resulted in a ramp-up period to get the programs into full swing. In addition, California had unprecedented mandatory water restrictions in place due to the historic drought for nearly all of FY 2016. This required more staff focus on water efficiency, and resulted in less staff time for our new electric efficiency programs. Program Highlight Our Commercial and Industrial Energy Efficiency Program is the flagship of our commercial portfolio. With three engineering firms working closely with our Key Accounts, this is where we get the bulk of our energy savings. The consultants assist our customers with audits, engineering studies, vendor selection, rebate processing and post installation inspection. They make the process as easy as possible for the customer. We are working on taking this program design into our residential market with the Home Energy Genie as the customer advocate.

Program Descriptions Commercial Programs:

• Commercial Advantage Program (CAP): Incentives offered to commercial customers for investments in efficiency lighting, motors, HVAC and custom projects that target peak demand and energy reductions. In FY 2016, CAP recorded a net annual electric savings of 334,645 kWh.

• Commercial and Industrial Energy Efficiency Program (CIEEP): This is the first year that CPAU expanded this program to offer Key Accounts the option of picking one of three engineering consulting firms to assist in helping them evaluate and implement energy efficiency projects. In FY 2016, CIEEP recorded net annual electric savings of 3,334,244 kWh.

• Empower: This is an ongoing program focusing on energy efficiency savings from mostly lighting retrofits in the small/medium commercial sector. In FY 2016, Empower recorded net annual electric savings of 372,598 kWh.

• Business New Construction (BNC): This program ended in FY 2016 due to the more stringent Title 24 requirements and our Palo Alto Green Building Ordinance (10% more efficient than Title 24) which make finding savings above our local code very difficult. Although the program is closed, we do have some customers with projects that are still on the books to be completed. During FY 2016, BNC recorded a net annual electric savings of 24,273 kWh.

• Commercial Benchmarking: This pilot program with GreenTraks, Inc. was implemented to assist 22 businesses with using the US EPA’s Portfolio Manager online energy management tool. Each building is benchmarked against similar buildings based on its energy usage using an Energy Star rating of 1 to 100. The goal of the pilot is to help a mixture of small, medium and large commercial customers benchmark their building and determine the best ways to remove barriers and encourage more customers to use Portfolio Manager.

Residential Programs: • MultiFamily Residence Plus+: This program provides no cost, direct installation of EE

measures to multifamily residences with 4 or more units including hospices, care centers, rehab facilities, and select small and medium commercial properties. The program has focused on energy efficient lighting and insulation upgrades. In FY 2016, the MultiFamily Residence Plus+ program recorded net annual electric savings of 105,514 kWh. In FY 2017, the program was revamped to include more LED lighting upgrades as the price of LED’s has decreased and the quality of the lights has greatly improved. We expect the savings to greatly increase for this program in FY2017, with a focus on upgrading below market rate apartment complexes.

• Home Efficiency Genie: The Home Efficiency Genie is our flagship residential program. Launched in June 2015, our residents can call the ‘Genie’ to get free utility bill reviews and phone consultations. For a fee, residents also have the option to receive an in-depth home assessment which includes air leakage testing, duct inspections, insulation analysis, energy modeling and a one-on-one review of assessment reports with an energy expert.

This package is followed up with guidance and support throughout home improvement projects. This program has a high educational value for Palo Alto residents. During FY 2016, the Home Efficiency Genie program recorded a net annual electric savings of 3,513 kWh.

• Smart Energy: This is a comprehensive energy efficiency incentive program for residential customers. The City gives rebates to residents who install energy efficient measures and equipment in their homes. Among these are attic insulation, heat pump water heaters, clothes washers, pool pumps, smart power strips and whole house fans. Due to federal minimum manufacturing standards for appliance efficiency, the number of appliances meeting rebate qualifying standards dropped significantly during FY2016. Compared to FY 2015, CPAU paid out 50.5% less in rebates under the Smart Energy Program. CPAU projects that this downward trend will continue. In FY 2016, Smart Energy achieved net annual electric savings of 48,564 kWh.

• Residential Energy Assistance Program (REAP): This program provides weatherization and equipment replacement services to low-income residents and those with certain medical conditions with no cost to the residents. This program has equal focus on efficiency as well as comfort, and therefore is not meant to be cost effective. In FY 2016, REAP recorded net annual electric savings of 22,907 kWh.

• Home Energy Report: CPAU stopped providing residents with individualized reports comparing their home energy use with neighbors in similarly sized homes in FY 2016. However, based on the results of behavior studies on Home Energy Reports, savings persist with a decay rate of 20% per year for 5 years after the program has ended. In FY 2016, the Home Energy Report recorded first year persistence annual electric savings of 1,283,418 kWh.

• Appliance Recycling: CPAU provided residents a $35 rebate to residents who recycle old, operational refrigerators with JACO Environmental which offered free pick-up and recycling services. In late November 2015, JACO Environmental went into receivership and shut down its operations. No energy savings for this program have been recorded for the FY16 period. Utilities staff is looking for a new program vendor and is working with the City Attorney’s office to terminate this contract.

Community Resource Education Programs: • CPAU offers free energy efficiency advice and energy education programs to the

community. Activities include hosting commercial Facility Manager Meetings for key account customers, residential energy workshops, participation in Chamber of Commerce meetings, neighborhood association events, local fairs and special events.

• In April 2014, CPAU announced its intent to compete for the Georgetown University Energy Prize, a national competition that aims to challenge communities across the U.S. to dramatically rethink their energy use. On January 14, 2015, CPAU was selected as one of the 50 communities in the U.S. leading the way on energy efficiency. The competition stretched over a two year period, ending December 2016, with a $5 million prize to be awarded to the winner of the competition. During this competition, CPAU developed an

online energy portal and worked closely with students and Cool Block participants to promote our programs and continue to save energy.

Public School Program: • CPAU provides an annual grant of up to $50,000 to the Palo Alto Unified School District

(17 schools with 12,000 students total) to support teacher training programs and the development of curriculums and education projects promoting energy and water efficiency. CPAU participates in monthly sustainable schools committee meetings and give educational presentations to classes on energy efficiency, renewable energy, and safety.

Complimentary Programs Customer-side Renewable Energy:

• Solar Water Heating Program: CPAU offers rebates to residential and commercial customers who install qualifying solar water heating (SWH) systems. The program is governed by state law in regard to development, implementation and administration.

• The PV Partners Program: Rebate funds were fully reserved in April 2016. The last PV installations are expected to be constructed by April 2018.

• SunShares Solar Discount Programs: Palo Alto has participated in regional group-buy solar programs in 2015 and 2016. These programs are administered by a non-profit agency and offer discounted prices for residential solar PV systems from a few pre-qualified contractors. The Peninsula SunShares program was offered to residents in 2015 (May through August) and resulted in 54 new solar PV installations in Palo Alto for a total of 236 kW. The Bay Area SunShares program was offered in 2016 (August to November) and resulted in 5 new solar PV installations in Palo Alto for a total of 28 kW.

Utility-interconnected Renewable Generation in Palo Alto:

• Palo Alto CLEAN: The CLEAN (Clean Local Energy Accessible Now) program offers a feed-in tariff for any sized renewable generation systems installed on the utility-side of the electric meter where all of the generated electricity is procured for use in Palo Alto’s Renewable Portfolio Standard (RPS). For fiscal year 2017, the prices are 16.5 ¢/kWh fixed for 20 or 25 years for solar renewable energy resources, up to a capacity limit of 3 MW (and 8.9 ¢/kWh for a 20-year contract term, or 9.1 ¢/kWh for a 25-year contract term beyond that limit), and 8.4 ¢/kWh for a 20-year contract term and 8.5 ¢/kWh for a 25-year contract term for non-solar eligible renewable energy resources.

• Community Solar Program: CPAU is currently developing a community solar program, which typically enable an electric utility’s customers to buy or lease solar panels in a centralized solar PV array and receive regular credits for the solar generation on their utility bill.

Research, Development & Demonstration: • The Customer Connect pilot program uses advanced meters to help residential customers

evaluate changes in their energy and water use and view their consumption through an online portal. This program has 400 participating customers, of which 96 customers have

enrolled in the pilot Time-of-Use electricity rate. Enrolled customers are able to save money by shifting electric usage to off-peak hours. The pilot also offers water leak detection and alert, staff notifies customers of both small and burst water leaks detected by the advanced meter system. Since November 2014, 222 individual water leak incidents have been detected. Staff communicated with the homeowners to resolve the leaks on over a quarter of the incidents, saving thousands of gallons of water from being lost and saving customers money. The pilot is planned to be extended until the end of 2020.

Program for Emerging Technologies (PET): CPAU’s Program for Emerging Technologies program (www.cityofpaloalto.org/UTLInnovation) provides the opportunity for local businesses to submit proposals to CPAU for review and potential pilot testing. The goal is to find and nurture creative products and services that will manage and better use electricity, gas, water, and fiber optic services. From its inception in June 2012 through July 2016, the PET program received 57 applications. PET pilot programs from FY 2016 include:

• linkAges Connect: Using Utility Data to Help Seniors and their Caregivers • Assessing the Environmental Value and Economic Performance of Residential Solar Water

Heating • Advanced Distribution Management System Testbed Development • Integrated Energy Storage System and Customer Portal consultation • Community Solar Program Management Software Suite

Demand Reduction Pilot:

• CPAU’s Demand Response (DR) pilot program offers incentives to large commercial customers to voluntarily reduce their electricity use during periods of high demand in the summer months. In the past three years, 1.4 MW (2014), 0.6-1 MW (2015) and 0.27 MW (2016) of loads were reduced during the peak demand period of the summer. This program has become an integral part of CPAU’s effort to reduce the reliance on fossil fuel generation and to lower purchase cost.

Evaluation, Measurement & Verification (EM&V) For FY 2016, CPAU contracted with TRC Engineers to undertake impact and process evaluation for the Commercial Advantage Program, Empower (Small & Medium Commercial) Program, CIEEP (Enovity & Ecology Action), MultiFamily Residence Plus+ Program and the Home Energy Report Program. A final EM&V report is expected to be available by March 2016.

PASADENA WATER AND POWER Pasadena Water and Power

• Climate Zone 9 • Number of retail customer connections: 65,308 • Retail Sales: 1,094.9 GWh ($181.3 million)

o Residential connections: 56,674 (32.9% of retail sales) o Commercial and Industrial connections: 8,629 (66.0% of retail sales) o Other: 1.1% of retail sales

• Budget for energy-efficiency programs: o $3.5 million expended for energy efficiency programs (includes incentives as well

as administration, program marketing costs and EM&V) o Funding Source: Public Benefits Charge (“PBC”) as authorized under Public Utilities

Codes 385(1) funds all AB1890 programs (current PBC revenue rate = $0.00685 per kWh)

o Energy-efficiency programs (rebates, distribution, direct install, marketing, administration, and program evaluation, measurement and verification) represent approximately 50% of Pasadena’s PBC expenditures. Solar incentive program represents 38%, Research Development and Demonstration (RD&D) represents 2%, and income-qualified rate assistance represents 11%.

Pasadena Water and Power Overview Trends in Pasadena which impact energy-efficiency programs include:

• Pasadena’s local economy continues to grow. o Rising real estate property values result in continued gentrification of older, lower

income residential neighborhoods; resulting in fewer income qualified households on rate assistance and eligible for income qualified efficiency programs

• New power rates became effective July 1, 2014 with an additional rate increases in July 2015 and July 2016.

• Given the ongoing draught in California, PWP has continued to focus on community outreach and awareness and creating innovative solutions for improving water efficiency and reducing customer water use.

• Aggressive energy-efficiency and demand reduction goals, adopted in 2013 by Pasadena’s City Council, combined with other changes in the market (e.g., new codes and standards) have continued to lead to flat energy load projections in the future.

Major Program Changes Major changes to the PWP energy-efficiency programs during FY2015/16 program year include:

• Implemented a successful LED promotion for customized energy-efficiency projects that was launched in Spring 2016 and subsequently extended until October 2016, to help

alleviate possible shortages from the unavailability of Aliso Canyon gas storage facility. This promotion successfully stimulated a large number of LED retrofits among Pasadena businesses; the majority of the savings will be reported in next year’s annual report.

• For residential customers, PWP launched a “Summer Readiness” Promotion with double rebates for residential customers in July 2016. This promotion will be reflected in next year’s annual report.

• Added additional measures to the LED WebShop, including smart thermostats and advanced power strips and added a smart thermostat rebate to the Home Energy Rebate program.

• Added several new programs including: to PWP’s portfolio of energy-efficiency programs including a non-residential Upstream HVAC program, and an income-qualified Energy Savings Assistance Program that is implemented through a partnership with the Southern California Gas Company (SoCalGas).

As additional PBC funding is becoming available as the funds required for large solar rebates decline, PWP anticipates launching a new residential direct install program in 2017. This program would provide comprehensive no-cost home energy and water audits by a trained efficiency specialist and install free energy and water products services, for residential customers, and support PWP’s focus on strong customer and community engagement. Measures and services planned include high quality LED light bulbs, showerheads, faucet aerators, toilet replacements, HVAC system ‘check ups’, and weatherization services such as ceiling insulation and weather-stripping, plus tips and customized guidance on additional energy and water upgrades with links to available incentives that will help customers save on their utility bills. This program would leverage co-funding through a partnership with SoCalGas and rebates available from the Metropolitan Water District. To further support small business and achieve additional water savings, PWP is also working to enhance the current energy and water direct install program (WeDIP) in 2017. PWP applied for a $1.2 million grant to expand this program over 2 years. This grant funding would allow additional water and energy saving product, to be available through the program, at no cost to participating customers. If the grant application is successful, PWP plans to target these benefits to small and mid-size businesses located in disadvantaged communities. Program Highlight In summary, below are the FY 2015/16 energy savings results by customer type (also see Tables 1 and 2 below):

Residential: 6,171 MWh Non-Residential: 8,807 MWh T&D and C&S: 4,442 MWh Total: 19,420 MWh

o WeDIP Program: All water and energy direct install projects completed were pre- and post-inspected.

Sources of Energy Savings PWP relies on the POU TRM data, where available, supplemented by best available technical data from independent engineering analysis where TRM measures are not yet available. For commercial programs, as discussed above, PWP relies on independent engineering analysis conducted by PWP’s engineering consultant and industry models (e.g., DOE’s eQuest building modeling software). The EEP program provide commercial customers with the ability to participate with any proven technology that saves energy, provided it meets the program requirements and the energy savings can be demonstrated.

Complimentary Programs • Low-Income Programs: PWP has offered electric rate assistance programs to eligible low

income seniors or disabled customers for several decades. The current Electric Utility Assistance Program (“EUAP”) became effective in 2006 and provides monthly assistance to low income, seniors, and medically-qualifying customers. Project APPLE (“Assisting Pasadena People with Limited Emergencies” provides a one-time utility bill payment assistance program that provides eligible customers who need help paying their bills, up to $100 per year. Funding for Project APPLE is provided through donations from PWP customers as well as PBC revenues. In addition, PWP in partnership with other City departments offers specific income-qualified services under the Under One Roof program to income qualified customers including low-to-no interest loans, exterior house painting, wheel chair ramps, weatherization services, an ENERGY STAR refrigerator exchange, solar energy systems, and turf replacement to drought tolerant landscapes, free of charge.

• Renewable Energy Programs: PWP’s Pasadena Solar Initiative (“PSI”) aims to install 14 MW of customer owned solar photovoltaic by December 31, 2017 in line with Senate Bill 1, California’s “Million Solar Rooftops” initiative. PWP offers incentives to encourage customers to install solar photovoltaic systems on their home or business. PSI incentives are paid upfront through an Expected Performance Based Buydown (“EPBB”) for smaller systems, whereas all systems larger than 100 kilowatts (“kW”) are now paid over two-years based on metered output through a Performance Based Incentive (“PBI”). Since the program started in 2008 and through June 2016, 872 PWP customers have participated in the PSI program installing 7.73 MW of solar power PWP also offers a Green Power Program, where customers can opt to pay a premium (2.5 cents/kWh) on their electricity bill for clean, renewable power. This program is open to both residential and commercial customers. As part of the 2015 PWP Integrated Resource Plan, approved by City Council in June 2015, PWP committed to support local renewable energy resources and community solar efforts and is currently developing a Community Solar pilot project and a feed-in tariff.

• Research, Development, and Demonstration: Throughout the years PWP has invested resources in a variety of different RD&D projects. This year, PWP continued to focus its support on Plug-in Electric Vehicle (“EV”) development by providing funding of City fleet electric vehicles. PWP has also secured grant funding from the American Public Power Authority’s Demonstration of Energy & Efficiency Developments program to install four solar powered heat pumps in Pasadena. Energy use related to heating and cooling indoor space makes up almost half of our customer’s total energy consumption. This project introduces a new technology featuring solar-powered heat pump air conditioning systems. Four units were installed at Pasadena Unified School District sites in December 2016. PWP is working with SCPPA and member utilities, to evaluate their effectiveness and to measure the product’s potential to reduce energy usage from heating and cooling. The evaluation is expected to be completed in March 2017.

• Electric Vehicles: PWP provided incentives for individuals who purchase an EV and/or install a Level 2 EV Charger at their Pasadena address. PWP provides up to $200 worth of LED light bulbs to residential customers for notifying PWP about their new electric vehicle. In

addition, PWP offers a bill credit of up to $400 to customers who install a Level 2 (240V) “wall mounted” or “hard-wired” charging station at their home, multi-unit complex, or business. The EV Charger incentive is also available to commercial customers and institutions for employees’ vehicle charging.

• PWP will continue to support the development of EV infrastructure in Pasadena and installed the City’s first Direct Current (“DC”) Fast Charger through grant funding that was received from the CEC. During FY 15/16, PWP installed the DC Fast Charger at the Del Mar Gold Line Station Parking Structure. The DC Fast charger enables rapid charging. Based on battery type and vehicle, DC Fast Charger can add about 60-80 miles of range to an EV in 20 minutes of charging time. This Fast Charger, currently free of charge, has proven very popular with EV drivers since it went into operation in December of 2015. Its use has increased and is now averaging 700-800 charging sessions per month.

During Fiscal Year 2015-2016, the annual PBF collection is $124,952 from electricity sales and $3,985 from natural gas sales. During Fiscal Year 2015-2016, $47,135 was expended on Commercial Lighting Retrofit Program and $45,266 was spent on Solar Incentive Program in the form of utility rebates. Unused fund in each program is carried forward to next year’s respective program.

Utility Overview Island Energy is a very small publically owned utility provides electric and natural gas distribution services to a decommissioned Navy base named Mare Island, which now hosts many different kinds of businesses and 287 residential homes. Most of the residential units were built in 2007 and 2008 with good insulation and high energy efficient appliances. Residential Energy Efficiency Programs include free onsite energy audits to make sure residents reach their energy efficiency goals. Most commercial buildings were built over 60 years ago. Now many of them have been refurbished and re-purposed for different kinds of businesses. Island Energy tailored its Commercial Energy Efficiency Programs to meet the needs of business owners on Mare Island. Island Energy provides rebates to these improvements to help lower business owners’ initial investments and shorten their payback period. Major Program Changes To encourage uses of electric vehicles on Mare Island, Island Energy has implemented rebate program for EV charging stations. Island Energy not only provides rebates for electric vehicle charger installations at residential/commercial premises, but also provides a block of energy at the lowest rate to electric vehicle customers. Program Highlight The Commercial Lighting program has the greatest impact among all Energy Efficiency Programs and contributes over 85% of energy savings to Island Energy’s Annual Energy Reduction Goal.

Rancho Cucamonga Municipal Utility Overview The amount of energy efficiency rebates in fiscal year 2016 have remained comparable to previous years with the main trend being lighting retrofits replacing inefficient lamps with LEDs. RCMU promotes the rebate programs and educates customers on energy efficiency practices in a customer newsletter, bill inserts and online. Free energy audits are currently being utilized to educate customers on energy savings and potential upgrades on existing equipment. RCMU continues to expand the existing distribution lines for projected future development and growth. Program Highlight The Energy Efficiency Rebate program continues to have the greatest impact and participation among RCMU customers. Lighting rebates continue to be the main focus with LED installations; however, RCMU has seen an increase in refrigeration and HVAC rebates and inquiries over the past year. Participation in the direct installation program has continued to be steady and popular with small businesses. The program has been a success because everything is taken care of for the customer and they can receive the benefits of the energy savings almost immediately with little to no cost to them. Program Descriptions

• Direct Savings Program – Non-Res Lighting: To encourage and assist small and medium sized businesses to reduce their energy usage, RCMU will pay and install up to $1,500 of recommended retrofit items that are determined from the complimentary energy audit. Any cost above the $1,500 limit is paid by the customer.

• Energy Efficiency Rebate Program – Non-Res Lighting, Non-Res Refrigeration, Non-Res AC: RCMU has adopted an “Express Solution” model for energy efficiency rebates. Customers receive a rebate for estimated kilowatt hour savings for the first year in the following categories: Lighting, Interior LED, Exterior LED, Delamping, HVAC, Motors and Refrigeration.

Complimentary Programs • Energy Audits: RCMU offers free, customized energy audits including lighting, HVAC and

equipment assessment and a review of energy usage. Specific cost-effective recommendations to improve energy efficiency and reduce energy use are provided.

• Renewable Energy Programs: In FY 2016, RCMU added three new solar customers into the service area that are estimated to save a total of 1,219,873 kWh per year. The program is currently open to small solar installations (<30kW).

REDDING ELECTRIC UTILITY (REU) Redding at a Glance

• Climate Zone -11 • Number of retail customer connections – 44,039 • Percent of retail sales by customer class – Residential 48%, Commercial 50%, Industrial

2% • Energy Efficiency (EE) Budget - $3.4 million. The EE programs are funded from REU

revenues as follows: $3.0 million Public Benefits charges, $ 0.4 million from general revenues. Expended $3.2 million, with remaining unspent funds carried over to the next budget year.

• Load Overview – Total sales for FY 2016 were 749 million kWhs, a 0.05 percent decrease compared to FY 2015. The forecasted average annual decrease for the next five years is 0.60 percent.

Utility Overview For the last few years, the Redding service area has experienced, as many other electric utilities have, a reduction in kWh sales compared to the level of electricity sales before the recent multi-year recession. Total sales for FY 2016 were 749 million kWhs - a 0.05 percent decrease compared to FY 2015. The slightly lower year-over-year sales figures for 2016 can be attributed to relatively mild weather, low economic activity and the impacts of EE programs. The forecasted average annual decrease for the next five years is 0.60 percent. This is mainly a result of a no-growth outlook based on population expectations, effective EE programs, and local economic conditions. Since the inception of REU’s Public Benefits Program and throughout the recent and continued challenging economic times, REU’s Public Benefits Program has been successful and well received in the Redding community. To date, around 70 percent (or more than two-thirds) of REU’s Public Benefits Program expenditures have been directed towards energy efficiency improvements. Because Redding is a relatively small and somewhat isolated service territory, REU has been able to build strong relationships with local businesses, including trade allies and the development community, to increase the awareness of cost-effective energy efficiency opportunities in new construction and remodeling projects throughout the community. These ties have proven to be most valuable when there is a viable need to increase or decrease a certain program and also in evaluating the addition of new programs. All EE programs need adjusting from time to time as building standards and technologies change. REU has an effective community outreach effort through the Energy Services Division’s (ESD) direct engagement with local energy product vendors, which makes it possible to have a continuously evolving and adaptable EE program. Major Program Changes To continue working toward improving REU’s operating efficiency and to further provide cost-effective efficiency improvements in our system, the Utility’s Thermal Energy Storage (TES)

program was expanded in FY 2014 to include new construction in addition to existing buildings within REU’s service territory. For FY2016 the amount of projects has maintained a constant pace. REU’s TES program focuses mainly on the 5 ton, direct expansion air-conditioning (DX-AC) market. This application of TES technology is provided with the addition of the Ice Bear® TES unit to qualified AC systems. In June of 2012, Redding entered into a multi-year, multi-million dollar contract to provide several megawatts of peak load shifting capability by 2017. Prior to 2012, Redding had been installing the Ice Bear® technology for several years to validate the application of this technology to REU’s customer base and unique (high peak demand, very low load factor) service territory requirements. With that considerable in-depth TES experience, it was apparent in 2012 an expansion of the program was warranted. In 2012 Redding was forecasting continual load growth and was faced with the expiration of a large power purchase agreement in 2015. Resource planning analysis was performed to find the best overall method to satisfy the forecasted increase in load growth and to fulfill the power supply shortfall. TES was identified as a cost-effective use of Public Benefits funds to partially fill that supply gap by shifting on-peak demand to off-peak periods and utilizing existing resources to fulfill the load requirements while at the same time helping to improve Redding’s deteriorating system load factor. Going forward, June 30th, 2017 marks the end of the 5 year TES contract and with the most recent load forecast indicating little to no growth, REU will be reviewing what role TES will play in future when considering all the expectations for statewide EE and Demand Side Management (DSM) goals under Senate Bill 350 (SB350). SB350 requires California’s load serving entities with annual sales exceeding 700GWh to conduct a comprehensive Integrated Resource Plan (IRP). The IRPs are to be designed to find the best approach in serving load in the most efficient, reliable and environmentally manner possible by utilizing a balanced combination of both supply-side resources and EE. It is expected that all current and future EE/DSM programs will be analyzed under REU’s IRP process. Even without the new IRP requirement, REU has always exercised sound business practices to routinely review the cost effectiveness of all resources used to provide all aspects of electric service to our customers. Program Highlight As mentioned above, REU’s operating efficiency is directly impacted by our summer air-conditioning driven peak system demand. The Utility’s Thermal Energy Storage (TES) program was significantly expanded in FY 2013 and continued to expand through FY2016. REU’s TES program focuses on the 5 ton, direct expansion air-conditioning (DX-AC) market. Redding’s commercial customer base has a significant amount of these types of units operating in a variety of businesses throughout the service territory.

The Ice Bears® serve to reduce the applicable AC systems’ peak demand on REU’s electric system by diverting the vapor/gas refrigerant in the DX unit away from the compressor and into a coil that runs through the systems’ ice block during the peak period. By relying on the temperature differential in the ice to condense the refrigerant back to the liquid state, rather than the mechanically driven compressor, the compressor does not run during the peak period of the day, and the AC load for the system is reduced by 95 percent for as much as six hours per day. Further, because the TES compressor is used during off-peak hours to re-freeze the storage systems’ water and make the ice that will later be used to provide cooling, the Utility “shifts” the load from on-peak to off-peak hours, thereby allowing the Utility to purchase or generate electricity during the cooler nighttime hours when it is more economically and environmentally efficient to do so. Shifting load to the nighttime hours also allows the Utility to consider more wind power (RPS qualified), which is more plentiful at night. With this nighttime operation, the compressor will typically run more efficiently than the same compressor running during the hottest hours of the day. Therefore, the customer will see a reduced amount of energy consumption (efficiency improvement) to provide a higher level of cooling comfort, and the Utility will see reduced operating costs as our load profile is flattened (operating efficiency/load factor improvement), a true win-win, cost-effective solution for all parties. This continued focus on peak load reduction will be increasingly important for REU because more than half of our demand is driven by air-conditioner load. With the required use of the newer refrigerant R-410A in DX/AC units, the new AC units being installed in California will be at least 5 to10 percent less efficient than older units that use R-22 when the temperatures exceed 105 to 115°F. Therefore, even though appliance standards require high SEER unit installation, these new units using R-410A will perform less efficiently at peak load times than older units with lower SEER ratings because the new refrigerant’s performance degrades substantially when ambient outdoor temperatures reach 105°F or more – a regular summertime occurrence in Redding. In FY 2016 REU installed 34 Ice Bear® TES systems. This brings the total systems in service to 251, providing nearly three megawatts of permanent load shift (PLS) capability. These systems are dispatchable, low maintenance (energy storage material is water), and long-lived, with at least a 20-year service life. Program Descriptions

• Appliances: Rebates for dishwashers, clothes washers, and dryers. Only makes and models on the current ENERGY STAR eligibility list qualify for a rebate.

• HVAC: Rebates for Heating, Ventilation, Air Conditioning, Duct Repair, Swamp Coolers, and Whole House Fans.

• Pool Pump: Pool Pump Program is only for programmable variable speed drive pumps installed on existing or new in-ground pools.

• Refrigeration: Rebates for Large and Small Refrigerators. Only makes and models on the current ENERGY STAR eligibility list qualify for a rebate.

• HVAC, Residential Shell: Weatherization Program – Consists of Insulation, Window Treatments, and Radiant Barrier.

• HVAC, Non-Residential Cooling: Rebates for Heating, Ventilation, Air Conditioning, Duct Repair, and Swamp Coolers. Commercial projects rebate levels are evaluated on a case by case basis.

• Lighting, Non-Residential: Lighting retrofit program has a pre-approval requirement that evaluates existing light vs. proposed new lighting to see if the project is eligible and is used as part of the process to determine the level of the rebate.

EM&V During the reporting period, REU had a third party review it’s Rebate Program during the first half of the 2016 calendar year. Adjustments were made to our Lighting program as a result of that review. REU is continuing to look at all of its programs for optimization and plans to update as appropriate rebate levels/program scopes in July 2017. Redding EM&V reports are available on NCPA’s Website: http://www.ncpa.com/current-issues/energy-efficiency-reports.html. Sources of Energy Savings REU, for the vast amount of its EE programs, uses the standard measures as constructed within the E3 reporting tool. For REU’s three unique programs (TES and Home Performance, and High Performance –New Construction) REU used the custom measure feature in E3 to model the energy and demand impacts of those programs. Complimentary Public Benefits Programs

• Renewable Energy Programs: REU’s Solar Program has been a great success. REU has seen significant interest in solar PV despite the lack of available rebates from the Utility through this reporting period. Though REU did not provide solar rebates over this reporting period, REU had 111 PV installations with an installed capacity of 862kW. Most of our PBI solar rebate commitments have been fulfilled freeing up additional solar rebate monies. REU will launch another round of rebates in September 2016. REU suspended photovoltaic installations on some (3) circuits/feeders. Distributed generation penetrations (including solar PV) greater than 25% have the potential to have a significant impact REU’s (and all utilities) ability to comply with Federal and State reliability requirements regarding both over voltage and under voltage issues as well as over frequency and under frequency cut out. Unfortunately, there will still be a limitation in certain areas. REU is working closely with local solar PV integrators/contractors on this issue as it continues to develop.

ESD staff, on a monthly basis, monitors the amount of funds collected and how they are disbursed (since program inception). This process enables REU staff to ensure compliance with SB 1 requirements and to make plans for an optimal program completion in 2017-2018.



Almost all of REU’s renewable resource development efforts are in the solar photovoltaic (PV) development area. PV development is currently a separate program in and of itself, as mandated by State Senate Bill 1’s passage and implementation. As a result, SB 1 funding has allowed REU to redirect dollars previously devoted to renewable development to low-income assistance.

• Low-Income Programs: Low-income assistance spending (through the CARES program and Lifeline Rate Discounts) continues to be the second largest area of our Public Benefits Program expenditures. During FY 2016, Lifeline support continued at the same amount, about $1.2 million. Low-income programs have been most beneficial to a significant portion of our customer base that has limited situational and/or financial means to participate in direct EE programs.

• Electric Vehicle(EV) Charging Infrastructure: In 2015 and 2016, to support electric vehicles in REU’s service territory, REU has held both internal and external committee meetings to work on determining suitable charging locations and procuring infrastructure to support this new and growing electric service. The external committee, Upstate Plug-in Electric Vehicle Coordinating Council (Council) is charged with bringing vehicle charging stations infrastructure to the Siskiyou, Shasta, and Tehama counties area. The Council’s main near-term goal is to facilitate installation of some of the first charging stations near main roadways running through the tri-county region. REU has had an increasing interest in services from customers who are buying electric vehicles. This new utility load may have impacts in several areas related to EE and DSM, both at the customer and utility supply and distribution levels. For example, whether electric vehicles are charged during the day or night may impact the cost and benefits of EE programs already in place. Redding will continue to work on this and other areas as to how electric vehicles will impact various utility operations. During the calendar year 2017, it is anticipated that at least one fast DC charger will be installed in Redding’s service area as a result of the efforts mentioned above. Additionally, REU staff is completing a comprehensive review of City of Redding’s fleet vehicle requirements with the expectation to have an EV plan proposal created the middle of 2017.

• High Performance –New Home Construction: A new housing subdivision was started in 2015, REU worked with the developer/contractor to incorporate innovative energy efficiency measures into the home designs similar to the measures used in our Home Performance Program. 13 homes were completed during this reporting period. These measures resulted in an Energy Code compliance margin or 45% to 50% above-code compliance. Some of the special features included HVAC equipment installed in conditioned space, deep buried ducts with R-50 insulation when not installed in conditioned space, Heat Recovery Ventilation (HRV) installed to provide both local and whole building ventilation, reduced air infiltration to an average of 1.6 ACH50. These measures help to reduce the needed HVAC system size to 1 ton of heating and cooling capacity for every 1500sqft of floor area. In addition to the HVAC system and envelope

measures, we also installed Heat Pump Water Heaters with a properly sized radial supply design. This shortened the time it takes for hot water to reach the fixture and reduces water wasted down the drain waiting for hot water to arrive. With a small 4kW to 4.5kW photovoltaic PV system, these home can be Zero Net Energy (ZNE) Homes. All homes were tested, air balanced and commissioned by REU and Consultant to verify all measure were installed according to project design and manufacture specifications.

Riverside Public Utilities Overview The regional economy has generally improved overall with the local unemployment rate within the City of Riverside falling to an annual average of approximately 6% for FY 15/16. Although showing a positive employment trend, these unemployment figures still remain somewhat higher than both the statewide and the national averages. RPU achieved 71% of the annual kWh savings goal of 1% of retail sales for FY 15/16. RPU assisted its customers in saving a total of 14.6 million kWh for FY 15/16. Although RPU did not reach its annual kWh savings goal in FY 15/16, the utility is cumulatively at 111% of the annual 1% goal since FY 10/11. The primary reason why RPU did not achieve the 1% kWh savings target in FY 15/16 was largely due to the ongoing statewide drought. RPU is a water provider as well as an electric provider. Therefore, it has been necessary to divert staff resources from energy efficiency to water efficiency programs in response to the aggressive water conservation goals established under the Governor’s mandatory drought regulations. This shift in resources had a substantial impact on reaching energy efficiency goals in FY 15/16. On a positive note, increased water savings has translated into some additional kWh savings as a result of the embedded energy in water production and delivery that has been avoided as a result of reduced customer consumption and aggressive water conservation efforts. The current rainfall

trend this winter is very encouraging and will hopefully result in the Governor lifting or relaxing the current water conservation regulations when the matter is reviewed in spring, 2017. RPU is a very important part of the local economy with a significant, positive economic and social impact. In an effort to measure this impact RPU commissioned an independent study in 2016 conducted by the UC Riverside Economic Forecasting Center. This comprehensive study estimated that the total economic impact that RPU generates in the local economy is nearly $500 million annually. This analysis also included the $7-10 million in annual expenditures of public benefit charge funding that also contributes to RPU’s economic impact in the local economy. Riverside Public Utilities is currently operating under an electric rate freeze originally adopted in 2010 by the City Council. This rate freeze has provided customers with stable and predictable rates; however the rate freeze is beginning to erode utility revenue in certain rate classifications. Public Benefit Fund revenue has also been impacted by this rate freeze. In FY 16/17 RPU will complete a comprehensive cost of service study of all electric rate classifications to determine if future rate adjustments should be recommended to the Board and City Council. RPU has experienced a modest expansion in the customer base and a 1% increase in load growth. Utility load growth has also lead to a 1% increase in retail sales. Major Program Changes RPU continues to enhance and expand its already extensive array of energy efficiency program offerings to its customers. The overall portfolio is examined quarterly for program requirements and incentive levels are adjusted up or down as necessary at the direction of the Utility General Manager. Although the local economy is much more stable and generally in a slow expansion mode, RPU is experiencing stagnant participation in energy efficiency rebate programs. Overall program participation has remained flat over recent program years at approximately 23,000 rebates per year. This flattening demand for energy efficiency programs is likely due to a combination of market saturation, overall cautious consumer confidence and customer perception that solar energy is more attractive than energy efficiency. Major changes or trends that impacted kWh savings in FY 15/16 include:

• RPU continues to see the rapid growth of customer participation in Property Assessed

Clean Energy (PACE) programs to fund energy efficiency and renewable energy projects. PACE programs can offer an important alternative financing vehicle for customers. In response to this popularity the Riverside City Council authorized an additional 10 PACE program providers in 2016 to enhance competition in the PACE financing market. One of the challenges is that PACE funded projects don’t necessarily increase participation in utility programs. Furthermore, PACE financing has not proven to be an appropriate or attractive energy efficiency financing vehicle for commercial customers. Other creative financing tools should be explored to specifically target the needs of commercial customers.

• Proposition 39 is resulting in some additional energy efficiency projects from local school districts and community colleges. Unfortunately these projects have been slow to complete

and have resulted in more modest kWh savings than had originally been projected. RPU continues to work with local schools using rebate programs to leverage Prop 39 funding.

• There is a growing trend in the energy efficiency field regarding the use of behavioral programs in order to enhance customer engagement and drive energy efficiency through impacting customer behavior. In 2016 the Riverside City Council approved a new customer engagement program and associated budget for a pilot program. RPU will be launching this new program to approximately 15,000 residential customers in FY 16/17.

• RPU successfully launched a 5MW thermal energy storage program using Ice Energy’s Ice Bear thermal energy storage technology. Approximately 40 Ice Bear units have been installed to date resulting in over 1 MW of peak load reduction and demand response in the first phase of the project.

• RPU’s Key Account Energy Efficiency Program (KEEP) is beginning to demonstrate substantial results. This program created several years ago was designed to go beyond the typical commercial customer facility audit and provide a comprehensive facility energy efficiency plan along with the technical expertise to assist the customer in implementing complex energy efficiency projects to drive substantial kWh savings. In FY 15/16 the KEEP Program assisted large commercial customers in saving over 2.3 million kWh.

• RPU’s LED retail buy-down program continues to grow in customer participation. Through local participating retailers, Public Benefit Funds are combined with GreenLite’s distribution platform allowing RPU to offer several LED lighting products at substantially discounted pricing for its customers. In FY 15/16 RPU customers purchased close to 35,000 energy efficient LED light bulbs through this program.

• RPU continues to experience increased activity and program participation in its multi-family and mobile home direct installation program. This program has allowed RPU to reach a market segment that was previously underserved. In addition, this program also focuses on the often overlooked energy efficiency opportunities such as lighting in the common areas associated with apartment complexes and mobile home parks.

Program Highlight RPU’s Small Business Direct Installation (SBDI) Program and Keep Your Cool (KYC) Direct Installation Programs continue to be a highlight of the overall program portfolio in terms of both customer acceptance and kWh savings. Although commercial customers only represent 10% of the total RPU customer base, the combined load of all commercial customers represents approximately 66% of the total utility consumption. With commercial customers representing the majority of the utility electric load, RPU has dedicated more programs and resources to assist the commercial customer segment in achieving energy efficiency goals. RPU’s small business customers have often been reluctant to participate in traditional rebate programs due to the lack of upfront capital and the lack of experience or technical ability to implement energy efficiency projects. In addition, small businesses often do not own their buildings, introducing barriers and motivational factors into the decision making process on whether to implement energy efficiency projects.

RPU’s Small Business Direct Installation Program was designed to address these primary customer concerns. The SBDI program is a comprehensive direct installation program combining measures such as high efficiency lighting retrofits and controls, HVAC tune-ups, LED exit and “open” signs, Tier 2 advanced power strips and various weatherization measures. The program is now available throughout the service territory and has been expanded to medium sized customers. SBDI offers businesses up to $2000 in free energy efficiency upgrades annually. Each project starts with an energy audit of the business facility to prioritize recommended energy efficiency measures that customers can pay for through a co-payment to the utility’s contractor for work above RPU’s incentive amount. RPU direct installation contractors continue to find that the market potential is substantial and that there is no shortage of businesses that can realize significant savings from energy efficiency upgrades provided through this program. Customer feedback regarding this program has been very positive with approximately 1500 commercial customers served in FY 15/16. The Keep Your Cool (KYC) Program is similar to the SBDI program, but specifically focuses on direct installation of cooling and refrigeration measures in mini-markets, delis, convenience stores and restaurants. Combined, the KYC and SBDI Direct Installation Programs have resulted in over 3.2 million kWh saved in this reporting year. Although on the higher end of measure costs within RPU’s program portfolio, the direct installation programs are still relatively cost effective at an average of $.50 cents per kWh saved. In addition, RPU receives additional benefits beyond energy efficiency from increased customer engagement and program participation as well as enhanced customer satisfaction through the direct installation programs.

EM&V

Riverside Public Utilities is committed to providing cost effective, ongoing evaluation, measurement and verification efforts for its energy efficiency programs. EM&V costs are covered in the individual program budgets.

In addition to periodic program audits, RPU consistently performs the following in support of EM&V activities:

• An onsite inspection rate of no less than 10 percent for all residential program

participants, performed by RPU staff and contractors. • In FY 15/16 RPU hired auditors, Baker Tilly to perform a comprehensive program

audit of all public benefit funded programs. The audit resulted in positive report with no major program findings.

• A pre- and post-inspection of 100% of commercial rebate participants, including a review of historical energy usage, energy-saving calculations and post measure bill analysis.

• All residential and commercial solar PV installations are field inspected and verified by city personnel for program compliance, system inter-connection standards and rated system production output.

• RPU contracts with the engineering firm Partner Energy to verify claimed energy savings on large, complex or technical commercial projects prior to issuing rebate incentives.

• Audits and installations performed by third-party contractors for RPU direct installation programs have high inspection rates that are performed by both the contractor and RPU staff.

• Refrigerator recycling program administered by Appliance Recycling Centers of America (ARCA) assures full inspection when the contractor picks up old appliances.

Sources of Energy Savings RPU Generally relies on the Technical Reference Manual (TRM) as adopted by the Public Utilities in California as the primary source for deemed energy savings used in the calculating and reporting annual program performance. If a specific measure cannot be found in the TRM, RPU will generally use a verified utility work paper or appropriate engineering/manual calculation as back-up documentation to justify claimed kWh savings and the specific measure is entered into the E3 reporting tool as a custom measure. Complimentary Programs

• Solar Rebate Program (SB 1) – RPU continues to promote residential and commercial participation in its solar rebate program to reduce peak load and offset customer electricity bills. In support of Senate Bill 1 (SB1) RPU has allocated a budget of $2.5 million annually through December 31, 2017 for customer installed systems. During FY 15/16, RPU issued rebates for 260 residential installations totaling 1646 kW AC and 10 non-residential systems generating 1170 kW AC of renewable solar energy.

• SHARE – This low income assistance program credits $150 annually toward electric deposit or bill payment assistance for qualified low-income RPU customers. In FY 15/16, RPU served approximately 4700 low income customers through the SHARE program for a total of over $700,000 in Public Benefit Funds credited to low income families for bill payment assistance.

• Research, Demonstration and Development (RD&D) – RPU continues to invest in RD&D programs through partnerships with both businesses and local higher education institutions. RPU has expended over $1,000,000 in Public Benefit Funds over the last ten years through its Energy Innovation Grant Program (see description above) to support energy research at local institutions of higher learning. Additional RD&D funding is provided to local commercial customers under the Custom Energy Technology Grant Program (see description above). RPU also participates in Southern California Public Power Authority (SCPPA) directed RD&D efforts and will continue to explore future RD&D opportunities as they occur on a case by case basis.

• Demand Response – RPU continues to manage a highly successful voluntary demand response program. This program, known as Power Partners, was developed in partnership with RPU’s largest commercial customers. These important Key Account customers agree to voluntarily shed or shift electric load during critical on-peak hours. This program became even more important in FY 15/16 due to the temporary closure of the Aliso Canyon natural gas storage facility impacting natural gas supplies in Southern California. Public Utilities like RPU rely on natural gas for internal generation power plants to manage summer peak electric loads. In response to this critical situation, RPU expanded the Power Partners Program resulting in a combined customer total of 23 MW of electric load that could be voluntarily shifted or shed in emergency situations. The Power Partners Program is effective during the peak summer months from June-September

if it is deemed necessary to call on this resource by RPU in cooperation with the CAISO and Southern California Gas Company.

• Pool Pump Timer Credit Load Shift Program – This program offers a bill credit of $5 per month for customers who agree to install and program their residential pool pump timer so that the pump operates only during off-peak hours. RPU has implemented an ongoing inspection program to inspect 100% of these timers for program compliance.

• GreenLite LED Retail Buy-down Program – RPU uses Public Benefit Funding to contract with GreenLite to buy-down the retail cost of certain LED light bulbs at participating local retailers to incentivize customers to purchase and install these high efficiency lighting products in their homes and businesses.

• Load Profiler Program (LPP) – RPU offers this program to all large Time of Use (TOU) customers. The service provides interval data as well as rate and usage analysis tools so that customers can view how and when they are using the most energy allowing them to make operational and behavioral changes to reduce consumption and avoid excessive demand charges.

ROSEVILLE ELECTRIC UTILITY Roseville Electric Utility at a Glance FY 15-16

• Climate Zone 11 • 58,002 retail electric accounts • Total customer sales were 1,189,977 MWh

o Residential 439,495 o Commercial 451,839 o Industrial 294,643

• Total energy saved from energy efficiency - 17,435 MWh • Total budget for energy efficiency programs - $4,552,385 • Total spent on energy efficiency rebates and educational programs - $5,230,081

Roseville Electric Utility Overview Roseville Electric Utility and the City of Roseville are prime economic drivers in the South Placer County region. Roseville ranks in the top 50 housing markets nationwide with over 800 new home permits issued in FY 2016. Commercial occupancy rates are strong across all sectors, most notably in Retail, Roseville Electric’s largest commercial sector. The strong economic climate supported residential and business investment in energy efficient exterior and interior LED lighting in FY 16 with 64% of the energy efficiency savings reported in FY16 coming from LED measures alone. This strong demand for LED lighting rebates resulted in Roseville Electric reporting 11,148 MWH from LED lighting retrofits in FY 16. Residential customers participating in the home energy reports behavioral program contributed an additional 17% of Roseville Electric’s energy efficiency savings for FY 16. Through the home energy reports program, Roseville Electric is able to educate customers with tips on conserving energy and about emerging technologies for the home. Roseville Electric will offer this program to all residential customers beginning in FY 18. Roseville Electric recognizes that customers perceived value in receiving incentives for energy efficiency upgrades. We will continue to design and deliver programs that offer a range of cost effective energy efficiency measures that are of interest to our customers and contribute towards achieving our energy efficiency targets while reaching out to educate customers on emerging technologies and behavior changes they can make at no cost. Major Program Changes Roseville Electric did not make any major changes to the energy efficiency programs in FY 16, however, changes made to the lighting programs in FY 15 in combination with a strong economy influenced customers to invest in LED lighting in FY 16. Several large commercial projects contributed significantly to the lighting savings reported in FY 16.

Roseville Electric expects LEDs to remain popular through FY 17 and FY 18 but anticipates a significant decline shortly thereafter as market saturation is reached. Program Highlight Roseville Electric began offering a few LED lighting measures to residential and commercial customers in FY 14. In FY 15, LED lighting represented 38% of the total kWh saved. In FY 16, LED lighting represents 64% of the reported savings. This represents lamps sold to residential customers upstream rebate programs at local retail locations (1,299,658 kWh) as well as indoor and outdoor LED retrofits of incandescent lighting in commercial buildings and parking lots (9,849,214 kWh). The Roseville Electric branded LED lamps sold through local retailers were well received by customers and successful primarily due to the low cost, high quality and variety of lamps sold through the retailer. Commercial customers were influenced to change out incandescent lighting to LEDs primarily because of the rebate offered by Roseville Electric. For many years, Roseville Electric residential customers requested rebates for whole house fans to assist with reducing summer cooling costs. In 2015, the measure was included in the POU technical resource manual allowing us to introduce rebates for our residential customers. Through education and promotion of whole house fans, participation in the rebate program doubled in 2016 and saved Roseville Electric 7,675 MWh. EM&V performed on the program in 2016 reported "Whole house fan survey respondents rated the incentive as the most important factor in their decision to install the product". Program Descriptions

Evaluation, Measurement and Verification (EM&V) EM&V is performed annually on one or two programs. Selection of the programs to EM&V is prioritized by the dollars spent and savings claimed for the program. The budget for pre and post EM&V is based on the program selected for review and can vary from $20,000 up to $150,000. The budget depends on the extent of field measurement or customer surveys required to fully evaluate the program within the guidelines established by the California Energy Commission. M&V is performed internally or by a third-party contractor on an ongoing basis for all programs. All EM&V reports are posted on the Northern California Power Agency (NCPA) website. http://www.ncpa.com/policy/reports/emv Recommendations resulting from EM&V and M&V reports are used by Roseville Electric in the design and/or redesign of energy efficiency programs.

http://www.ncpa.com/policy/reports/emv

Recently completed EM&V include: • HVAC Right Size (2013) • Small Commercial and Multi Family Rapid Audit and Install (2014) • Residential HVAC, Pool Pump, Whole House Fan and Sunscreen (2016)

Sources of Energy Savings Roseville Electric relies on the savings in the E3 model provided by the TRM. If not available, the measure is entered to the E3 model as a custom measure. When a custom program is entered to the E3 model, the source of energy savings comes from a white paper, prior EM&V or a manual watt to watt calculation using customer provided hours and baselines. Roseville Electric relies on customer hours for some industries if they are more accurate in actual application than the hours in the TRM.

• LED Lighting: Roseville Electric relies on TRM LED lighting measures when available in the E3 model; otherwise Roseville Electric relies on industry specs for watts and replacement data (incandescent or cfl) and calculates savings using the TRM hours of operation and replacement of incandescent lighting as the baseline. Roseville Electric assumes baseline of incandescent as few residential or commercial customers adopted CFL technology.

• New Home Development Agreements: Roseville Electric is involved in all specific plan

negotiations with new home builders in Roseville and is able to enforce the requirement that all new home builders install HVAC systems with higher SEER and EER ratings than required by Title 24.

• New Home Construction Rebate Program: Roseville Electric influences the construction of

new homes in Roseville by providing rebates to participating builders for energy efficiency and solar. The energy efficiency savings are calculated using the Title 24 reports submitted for each participating village and rebated for energy efficiency by the percentage exceeding state housing standards.


• Renewable Energy Programs: Roseville Electric rebated $837,289 on residential and commercial solar systems in FY 2016 adding 673 new systems. As of December 31, 2016, Roseville Electric had 3,083 installed solar systems at 11.3 MW.

• Multi Family Audit and Direct Install: Roseville Electric spent $102,422 to assist multi-

family residents in Roseville through a contractor energy audit program. The contractor performed an in - home energy audit providing the resident with prescriptive instructions to conserve energy.

• Low-Income Programs: Roseville Electric offers several rate assistance programs for

qualified low income residential customers. Roseville Electric spent $271,798 providing

SACRAMENTO MUNICIPAL UTILITY DISTRICT (SMUD) SMUD at a Glance

• Year established: 1946 • Climate Zone: 12 • Total Customers (year-end): 617,307 • Percent of retail sales by customer class – 46% residential, 54%

commercial/industrial/other • SMUD spent $32.0 million for residential and commercial energy-efficiency programs,

compared to a budget of $34.2 million.1 All expenditures are public-goods funded. SMUD Overview SMUD is planning program changes to respond to the following industry trends and changing customer expectations:

• Dozens of new companies now provide products and value-services that involve devices networked through the utility meter, WiFi, or cellular bands.

• LEDs: Prices are declining rapidly due to a combination of increased economies of scale, manufacturing technology improvements, and competition.

• The goals and expectations surrounding SB350 are due toward the end of 2017, which could cause significant changes in budget and goals for energy efficiency.

• The Comprehensive Energy Efficiency Program for Existing Buildings authorized by AB 758 will ultimately generate new utility data reporting requirements, additional building assessment and rating tools and requirements, an increased emphasis on efficiency code compliance during retrofits, focus on building industry training programs, and potential requirements for utilities to finance building upgrades.

• Residential rates will begin to mimic commercial rates at SMUD, with a movement toward TOU rates. This will place a greater focus on measures that impact peak demand and load management strategies.

• Commercial customers’ interest in Zero Net Energy (ZNE) solutions is growing. • More and more customers prefer to access information and communicate via mobile

devices. • Consumers are becoming increasingly interconnected, fundamentally shifting channels of

social interaction. • Customers want clear and simple choices

Major Program Changes The overall budget, energy and peak savings achieved in 2016 were relatively unchanged from 2015. But the following program changes were made to facilitate customer demand and prepare for the future:

1 Includes market research, planning, M&V, and emerging technologies R&D.

• The Retail Lighting program delivered less savings as the movement continued toward an LED only program and the eventual sunset of the program. The program went from a product mix of 60% LEDs and 40% CFLs in 2015 to a product mix of 90% LEDs and 10% CFLs in 2016. The program was able to accomplish this by lowering the incentives to both CFLs and LEDs.

• In conjunction with further improvements to Energy Tools using an OPower platform, SMUD added Business Energy Reports to the existing, 50,000 customer, Home Electricity Reports.

• In collaboration with the EPA, SMUD continued to support and offer the Retail Product Platform (RPP) program, which incentivizes retailers to stock up, and make available greater Energy Star Products. For the 2016 program, new national retailers were added, and new products like heat pump dryers, and sound bars were included. Through the 4 participating retailers, over 7400 products were incentivized.

• The Home Performance Program more than doubled over the past year as the local contractors embraced the program and for several contractors it became the marquee component of their product offerings. While this program took several years to reach maturity, continued to growth is expected for this program.

• SMUD awarded a new three-year contract to Ecology Action to run the Complete Energy Solution program. This program is designed to provide comprehensive energy efficiency solutions to the smaller and mid-size commercial customers. In the latest version of the contract, the vendor has been asked to reach deep into the energy efficiency potential of these traditionally underserved customers. Ecology Action voluntarily set aside a portion of the program to focus on non-profit organizations.

Program Highlight While the Retail Lighting program reduced in size by about 5%, the program continued to make tremendous strides in transferring into an LED only based program. Based upon the reduction of cost and the increased availability of LEDs, this program has become an LED only program for 2017. LED light bulbs are a much better customer experience than CFLs. Customers can expect a higher quality light source with better startup characteristics and better overall controllability. Based upon the continued reduction in LED light bulb prices, the LED light bulb has become viable for nearly every light bulb in the typical house. Program Descriptions SMUD has been continuously operating energy-conservation, load management, and energy-efficiency programs since 1976. Over that 40 year time period, SMUD’s customers have saved over 2 TWh of first year energy savings. In 2007, the SMUD Board of Directors approved a significant expansion in annual savings goals for its energy-efficiency resources, from approximately 0.6% of annual sales to an annual average of approximately 1.5% over the following decade. These goals have now been extended through 2023. The expanded goals were part of the Board’s vision to “empower our customers with solutions and options that increase energy efficiency, protect the environment,

reduce global warming, and lower the cost to serve our region.” SMUD is continually redesigning its energy-efficiency portfolio to expand existing programs, plan and implement new programs, and develop and implement a broader marketing and engagement plan that will meet these expanded goals and the Board’s vision. For 2016, SMUD spent $32.0 million for residential and commercial energy-efficiency programs, compared to a budget of $34.2 million.2 All expenditures are public-goods funded. These programs delivered 35.9 megawatts (MW) of peak-load reduction and 169.2 million kilowatt-hours (GWh) of annual energy savings, compared to annual goals of 28.5 MW and 158.0 GWh. These goals do not match the reported saving on the attached spreadsheets due to variations between net to gross accounting. For 2017, residential and commercial energy-efficiency programs, SMUD has budgeted $28.1 million in PG funds.3 These programs are projected to deliver 39.3 MW of peak-load reduction and 158.5 GWh of annual energy savings. These goals do not match the reported saving on the attached spreadsheets due to variations between net to gross accounting. Commercial/Industrial Retrofit Programs Expenditures for commercial/industrial energy efficiency retrofit programs for existing buildings and facilities were $13.0 million, with delivery of 10.1 MW of peak-load reduction and 74.5 GWh in annual energy savings.

• Customized Energy Efficiency Incentives: Promotes the installation of energy-efficient equipment, controls, and processes at commercial and industrial customer facilities. Provides incentives to contractors and/or customers to promote the installation of energy efficient lighting, HVAC, motors, and refrigeration equipment and controls. The program also provides incentives for retro-commissioning, process improvements, and data center storage projects that result in energy savings.

• Express Energy Solutions: Provides prescriptive incentives to participating qualified contractors for high-efficiency equipment across a variety of end-uses: lighting, HVAC, refrigeration, and food-service equipment. Incentives are targeted to the contractor/supplier in an effort to stimulate the market for energy-efficient equipment and services, and are designed to cover a significant portion of the incremental cost of the equipment.

• Complete Energy Solutions: Third party administrator performs comprehensive energy audits of small and medium-sized businesses. Customer receives a customized report detailing recommended energy improvements, estimated savings, estimated cost and payback. Third party administrator then assist customer in hiring a contractor to complete the project.

• Savings by Design: Provides incentives to builders and their design teams to design new commercial and industrial buildings 10-30 percent more energy efficient than required by

2 Includes market research, planning, M&V, and emerging technologies R&D. 3 Includes market research, planning, M&V, and emerging technologies R&D.

Title 24 (or typical new construction in the case of Title 24-exempt buildings and processes).

• Prop 39 Schools Program: SMUD has taken the position of a trusted advisor with regard to the Prop 39 funding that has been made available to schools for retrofit projects. Instead of a traditional rebate program, SMUD has provided consultant services to help facilitate the local school districts’ access to the Prop 39 funds. Since we still have aided with projects and the schools are using Prop 39 funding, we have included our costs in our reporting, but we have not added the schools cost for the projects as participant costs.

Residential Programs Expenditures for residential energy-efficiency programs for existing homes were $15.3 million and achieved 19.9 MW of peak-load reduction and 73.5 GWh in annual energy savings.

• Shade Trees: Provides free shade trees to SMUD customers. Implemented through the community-based non-profit Sacramento Tree Foundation (STF). STF foresters review tree selection and site locations with customers, who plant the trees.

• Equipment Efficiency: Provides rebates and/or SMUD financing for qualifying (Energy Star, Consortium for Energy Efficiency, and/or other high-efficiency) efficiency improvements to homes’ building shells and equipment. Improvements include central air conditioners and heat pumps, windows, heat pump water heaters, and cool roofs.

• Home Performance Program: Participating contractors use building-science principles and diagnostic equipment to evaluate the current performance of the whole house, and then recommend comprehensive improvements that will yield an optimal combination of savings and comfort for homeowners. Once the homeowner selects the improvements that fit their needs and budget, participating contractors will do the work to Building Performance Institute standards.

• Plug Load Program: Provides rebates for qualifying (Energy Star or Consortium for Energy Efficiency-listed) appliances: clothes washers, dishwashers, refrigerators, and room air-conditioners. Also included in this program are Refrigerator/Freezer Recycling, Pool Pumps and the Retail Partnership Program. Refrigerator/Freezer Recycling provides rebates for the free pick-up and environmental recycling of old refrigerators and freezers. Pool Pump rebates are available to customers and contractor for installing high-efficiency variable-speed pool pumps. The pool pump program also focuses on educating the pool-contractor community on practices for retrofit and new-pool installations that maximize pumping efficiency and minimize energy use and peak demand. The Retail Partnership Program is an upstream program that works with big box retailers to pay retailer incentives for all the energy efficiency items they sell in their stores.

• Retail Lighting: Promotes energy efficient residential lighting products by providing incentives for manufacturers and their retail partners to sell Energy Star lighting at a discount. Implemented through agreements with manufacturers and retailers that involve cost buy-downs, marketing, and/or advertising. SMUD has been steadily increasing the percentage of LED bulbs rebated through this program.

• Multi-Family Retrofit Program: The Multifamily (MF) Retrofit Program contains two distinct options for MF property owners: (1) Home Performance Program for Multifamily (HPP-MF) Rebates, which provide comprehensive retrofit of existing MF buildings (such as at least two changes to an existing building’s envelope, electric water-heating system, space-conditioning system, or lighting system); and (2) Prescriptive MF Rebates, which is offered to MF property owners who are not willing or able to invest in major comprehensive energy efficiency improvements. This program will be on hiatus for 2017.

Information/Education Programs Expenditures for information and Education programs were $1.0M in 2016 with 5.8 MW of peak-load reduction and 21.2 GWh in annual energy savings.

• Home and Business Electricity Reports: A scientifically designed program to measure the impact of sending electricity-usage reports to residential and commercial customers. The reports compare the customer’s monthly usage to that of the previous year and to about 100 neighbors in similar-size homes with the same heat energy source. The reports are customized to each house or business and provide energy tips to assist the customer in making behavior changes that reduce their energy use.

• Residential Advisory Service: Provides on-site energy audits of homes, on-line energy audits, and telephone assistance for customers, with recommendations to reduce their homes’ energy use (and bills). Recommendations include practices and home-improvement projects that will increase the energy efficiency of their dwellings.

Demand-Reduction Programs • Residential Air Conditioner Load Management Program: In the past, customers volunteered

to allow SMUD to install a radio-controlled cycling device on their central air conditioners, and to send a radio signal that switches or cycles off their air conditioners during an electric-system emergency. In the late 1990’s the program was transitioned over into maintenance mode with installation being stopped and then in 2010 the program was shut down and all service and maintenance related work was discontinued. In an Emergency Situation the Power System Operators do have the ability to activate the entire ACLM cycling program within a 3 minute time span.

• Residential PowerStat Program: PowerStat is a “customer choice” model for residential customers giving them more options to manage their energy costs as well as providing comfort and convenience. The PowerStat pilots included a variety of customer tests with varying degrees of incentives and temperature setbacks, with different limitations on event overrides. These pilots were shut down in 2016.

• Power Direct (Automated Demand Response Program): Enhances facilities’ energy performance by seamlessly integrating automated response capabilities into energy management, lighting and HVAC systems. Automatically reduces electricity consumption on Conservation Days in times of high demand.

EM&V SMUD has established a framework to develop yearly measurement and verification (M&V) action plans. SMUD is planning M&V activities for all of its major programs, scheduled at fixed intervals (2-4 years apart), with the intention of evaluating all programs on a continued cyclical basis through 2020. For methodological approaches needed to perform specific types of evaluations, SMUD will be guided by the CPUC’s “California Evaluation Framework” (June 2004) and “California Energy Efficiency Evaluation Protocols” (April 2006). SMUD is planning to allocate approximately one percent of its total energy-efficiency budget towards impact- and persistence-focused M&V studies. These studies will be conducted primarily through the use of third-party contractors, with management and oversight by SMUD’s Business Planning Department. SMUD completed the following M&V activities in 2016:

• Savings by Design • Pool Spa and Pump

In 2017, M&V will be conducted for the following: Sources of Energy Savings In order to determine energy savings, programs may rely on several sources: the Database for Energy Efficient Resources (DEER), TRM, Energy Modeling Software, or specific studies conducted by utilities or recognized working groups. The goal is to use the most current studies/workpapers which best represent CZ12 and SMUD customers. Complimentary Programs

• Smart Homes- New construction program that integrates energy efficiency, demand response and other technologies in an aligned vision. The program is designed to complement SMUD’s other portfolio programs (EE, DR, EV, etc.) to support SMUD’s future load requirements. The resulting home design from those builders that participate will be an innovative use of energy-efficient design technologies, integrated built-in DR capabilities, automated peak shifting strategies, and other “smart” connected options desired by homeowners.

• Renewable Energy Programs: Incentives for net-energy-metered PV; a feed-in tariff for mid-scale systems (currently closed); voluntary green pricing programs including SolarShares, which supports expansion of distributed PV; commercial and residential REC purchase programs; and a community solar program aimed at enhancing K-12 curricula on renewable energy.

• Low-Income Programs: SMUD provides a low-income rate subsidy, a medical assistance rate subsidy, and no-cost weatherization services to our low-income customers. Pilot programs are currently in-place to try other energy efficiency options to assist our low-income customers.

• Research, Development, and Demonstration: SMUD has a centralized research and development program that conducts public good research across the electricity enterprises

from the supply side to demand side. With an annual budget of approximately $10.8 million, research is conducted in eight research areas which include renewable energy, electric transportation, climate change, distributed generation, energy efficiency, demand response, storage and smart grid. These programs seek to track emerging technologies, demonstrate promising technologies and prepare SMUD and SMUD customers for adoption of these emerging technologies.

• Codes & Standards: SMUD continues to assist with the development and implementation of codes and standards (e.g. T24, T20, etc.). SMUD participates in several working groups, drives code compliance through programs, assists with workforce training, conducts research, and develops data management systems to improve tracking and reporting. SMUD is planning to claim the energy savings associated with the Codes and Standards work starting in 2017. SMUD claims the Codes and Standards cycles in which we have previously participated. Electric Vehicles: In 2016 SMUD’s Drive Electric program promoted adoption of plug-in electric vehicles through special PEV rate offerings, participation in educational events, educational offerings through our website SMUD.org/PEV, and collaboration with local auto dealers and the local EV advocacy group Sac EV. SMUD’s coordination of a large scale Ride-N-Drive event at the Sacramento International Auto Show resulted in test drives of plug-in electric vehicles and was one highlight of our PEV education efforts.

• Energy Storage: SMUD conducted field studies to examine grid-scale storage applications, risks and benefits. Additionally, residential applications for storage combined with renewable generation and dynamic pricing were also tested in a midtown Sacramento new construction development.

SAN FRANCISCO PUBLIC UTILITIES COMMISSION San Francisco Public Utilities Commission At a Glance

• Providing electricity to customers since 1925. • Located in Climate Zone 3. • Serving approximately 2,400 retail customer connections . • Customer classes: Approximately 40% of retail electricity is supplied to San Francisco

municipal customers in the “General Fund” rate class, consisting primarily of nonresidential buildings, process loads, and streetlights. The remaining retail electricity is supplied to customers in the “Enterprise” rate class, which are primarily municipal nonresidential buildings, tenants on municipal property, multi-tenant residential buildings, and process loads.1

• FY 2015-16 total electricity sales to retail customers: 968,000 megawatt-hours (MWh); peak demand: 147 megawatts (MW); load growth is negligible.

• In FY 2015-16, the Power Enterprise appropriated $1,000,000 for energy efficiency projects other than streetlights. Actual spending of utility revenues (reporting all project costs in the year of completion) totaled $1.3 million. Other public purpose programs include municipal renewable energy projects and the GoSolarSF solar incentive program.

San Francisco Public Utilities Commission Overview Power Enterprise manages a portfolio of electric generation, which includes the SFPUC’s Hetch Hetchy Water and Power system, which generates an average of 1.6 million MWh of clean hydroelectric power each year, 23 municipal solar photovoltaic installations (8.1 MW), and 2 biogas cogeneration facilities (3.1 MW). Power Enterprise has made a commitment to energy efficiency as its highest priority resource. Historically, Power Enterprise’s energy efficiency programs mainly have targeted its municipal customers, and most of its programs have been provided at no charge to these civic agencies. Today, fee-for-service programs represent a growing portion of energy efficiency offerings. Power Enterprise is also developing new programs for its growing residential and commercial customer sectors. Major Program Changes This year’s energy savings are primarily derived from completion of a number of comprehensive HVAC retrofits of older municipal buildings located downtown, which also resulted in substantial natural gas savings. Additionally, Power Enterprise continued to implement commissioning and design review projects to achieve electricity and natural gas savings at various sites. Finally, Power Enterprise continues to achieve significant savings through LED streetlight retrofits, which are expected to significantly increase in scale, starting in the next fiscal year.

1 A small portion of sales are made to non-municipal residential and commercial customers located in redevelopment projects at Treasure/Yerba Buena Islands and Hunters Point that are served off of Power Enterprise operated distribution systems.

Program Highlight Energy efficiency has been an essential component of Power Enterprise’s resource portfolio for more than a decade. In the current reporting period, FY 2015-16, completed energy efficiency projects are estimated to save 1,100 MWh (net savings) of electricity per year, at a utility cost of $1.3 million. Program level highlights for FY 2015-16 include:

• Direct-install style retrofits provided most of the electricity savings reported for this fiscal year, including HVAC upgrades at major parking garages and major Real Estate Division buildings.

• Power Enterprise provided ongoing design review for new construction and commissioning for the renovation currently being completed at San Francisco International Airport.

• 718 streetlights were replaced with LED technology. Power Enterprise plans to eventually convert 18,000 streetlights to LED.

• Power Enterprise’s annual report benchmarking the energy performance of San Francisco’s municipal buildings includes 465 buildings representing almost 49 million square feet of building area.

Program Descriptions Power Enterprise’s energy efficiency programs are generally tailored to the particular customer’s circumstances because most customers are large and have varied property characteristics. They include:

• Direct-Install Program: This program provides complete retrofit services to targeted municipal customers, usually at no cost to the customer. The program focuses on City agencies that are funded primarily through local tax receipts, fees, and federal/state-funded programs. These customers are considered hard-to-reach (due to limited access to capital and engineering, as well as insufficient price signals).

• Civic Center Sustainability District: Through a partnership with the Clinton Global Initiative, this program demonstrates green, renewable and energy efficient technologies as a national model for sustainability in historic districts. For energy efficiency projects, the program provides free energy audits, design, construction management, construction services, and full funding to buildings in the City’s historic district.

• LED Street Light Conversion Project: The capital-funded program aims to convert about 18,000 high pressure sodium street lights to LED lights. The program will reduce energy use and maintenance costs, and improve pedestrian and vehicular safety. The project scope includes the installation of networked wireless controls, which will further reduce energy consumption via fixture dimming. The project launched in FY15-16. This year, 718 streetlight fixtures were replaced with LEDs, with a projected annual electricity savings of 293,000 kWh.

• Green Commissioning and Design Review Program: Power Enterprise provides commissioning and related green building design review services on a fee-for-service basis for municipal new construction and major renovations. For existing buildings, the program offers retro-commissioning services.

• Energy Benchmarking Program: San Francisco requires owners of non-residential buildings over 10,000 square feet to annually benchmark and disclose the energy performance of their buildings. In FY 15-16, Power Enterprise released its fourth annual report benchmarking the energy performance of San Francisco’s municipal buildings, including 465 buildings representing nearly 49 million square feet of building area.

EM&V Historically, the majority of energy efficiency retrofit projects funded by Power Enterprise have included an individual M&V study following the International Performance Measurement and Verification Protocol (IPMVP). These projects have included an M&V plan with a sampling plan, a logging plan, an approach to data recovery and analysis, and a written report. Sources of Energy Savings Power Enterprise’s mostly-direct-install energy efficiency portfolio allows it to report energy savings based on site-specific engineering studies with detailed ex ante savings estimates. These studies base savings on on-site collected data for hours of operation, nameplate data for replaced equipment, and detailed site-specific costs. Complimentary Programs Power Enterprise offers several related programs, among them:

• Renewable Energy Programs: o Municipal Renewable Program: Under this program, Power Enterprise directly

installs, maintains and operates solar PV systems on municipal buildings throughout the City and County of San Francisco; and

o GoSolarSF: The program provides incentive payments to San Francisco residents and businesses installing rooftop solar projects. The program includes a component for low income residents, which complements a statewide program administered by Grid Alternatives, a nonprofit organization.

CITY OF SHASTA LAKE City of Shasta Lake At a Glance

• Climate Zone 11 • Number of retail customer connections: 4,542 • FY15-16 total retail sales revenue by customer class (35% residential, 10% commercial,

and 55% industrial) • FY15-16 total budget for Public Benefit Programs: $359,461 • FY15-16 total amount actually expended for energy efficiency programs: $107,025

City of Shasta Lake Overview The CSL feels a significant responsibility to its community to invest their Public Benefits funds in such a way as to impact both energy and financial savings for their customers, and a positive economic impact in CSL as well. CSL offers a comprehensive menu of rebates to all of our customers. However, because of the economic downturn that has affected the City for several years, the number of customers taking advantage of the rebate offers have been relatively low. Program Highlight The Commercial Lighting Program delivered 65% of the total kWh savings in FY16. While CSL accomplished 21% of the target kWh savings for FY16, 110% of the total annual goal since FY11 have been realized. History has demonstrated that direct install programs are beneficial and customers will take advantage of free give-a-ways. Program Descriptions CSL manages a comprehensive energy efficiency incentive program for residential and commercial customers focusing on energy efficiency and peak load reduction. For residential customers, rebates are offered for the installation of various energy efficiency measures, such as lighting, HVAC, appliances, and weatherization. For commercial customers, rebates are available for upgraded lighting, HVAC, appliances, refrigeration equipment, electronics, and in cases where an analysis is performed rebates can be offered for additional equipment that reduces energy use and/or demand. On-site energy audits are provided by CSL energy specialists. Energy efficiency measures are recommended and additional visits are completed upon request.

• Residential Lighting Program [Res Lighting]: CSL offers rebates to homeowners who install ENERGY STAR® qualified LED lamps/bulbs, ceiling fans and LED holiday lights.

• Residential HVAC Program [Res Cooling]: CSL offers rebates to homeowners who install high performance heat pumps, central air-conditioners, room air-conditioners, whole house fans, or evaporative coolers that exceed current state requirements. CSL also offers a rebate for duct sealing when not required by code.

• Residential Equipment Program [Res Clothes Washers; Res Dishwashers; Res Pool Pump; Res Refrigeration]: CSL offers rebates to homeowners who purchase new ENERGY STAR

qualified products, including clothes washers, room air conditioners, dishwashers, pool pumps, and refrigerators.

• Residential Weatherization Program [Res Shell]: CSL offers rebates to homeowners who invest in weatherizing their homes, including attic and wall insulation, window treatments/replacement, air/duct sealing and radiant barriers.

• Residential Water Heater Rebate Program [Res Water Heating]: CSL offers rebates to homeowners who purchase a new, energy efficient electric water heater.

• Commercial Lighting Program [Non-Res Lighting]: CSL offers rebates to business owners who invest in the installation of energy efficiency lighting upgrades. There is a prevalence of inefficient lighting throughout the city and most high bay lighting uses high intensity discharge fixtures instead of more efficiency fluorescent or LED fixtures.

• Commercial Custom Program [Non-Res Comprehensive]: CSL offers rebates to business owners based on site-specific consumption. Rebates are tailored to the individual business owner’s needs based on the audit and the potential energy savings associated with the customer project.

EM&V EM&V report link http://www.cityofshastalake.org/DocumentView.aspx?DID=148 “ERS assessed CSL’s WEPT program and estimated its potential energy savings as 22,826 kWh. CSL’s regulatory compliance report for FY2015 was reviewed and verified as accurately representing the energy savings performance of the energy efficiency programs.” Sources of Energy Savings The 2016 TRM was the source for most of the claimed savings. The Commercial Lighting Program relies on custom savings calculations. Complimentary Programs

• Low-Income Programs: Lifeline monthly rate discount program and one time bill assistance known as SHARE

• Renewable Energy Programs: Focus on customized solar projects that benefit the City • Research, Development, and Demonstration: Focuses on LED lighting in various

applications, community solar charging station(s), and latest HVAC applications in City owned facilities

• Electric Vehicles: Support of local business in conversion of combustion engine vehicles to electric vehicles. Currently participating in a regional transportation study to electrify buses.

SILICON VALLEY POWER

Silicon Valley Power at a Glance • Climate Zone 4 • 53,235 retail customers; 85% are residential; 14% are commercial & industrial; 1% are

municipal • Retail Sales Breakdown: 7.2% residential, 2.9% commercial, 89.4% industrial, 0.6%

municipal (Note that commercial and industrial customers are categorized by their rate code, and not type of business performed at the location.)

• The amount budgeted for energy efficiency programs in FY 15-16 was $6,665.846. • The total amount actually expended was $3,989,874. All funding for energy efficiency

programs comes from the Public Benefits Charge on customers’ utility bills. Unexpended energy efficiency dollars are typically rolled over into the following fiscal year’s energy efficiency programs. However, at the end of Fiscal Year 2015-2016, SVP had built up a larger than usual reserve, so SVP will be reallocating a portion of the unexpended commercial energy efficiency program funds from previous years to fund the FY 2016-2017 PV rebates that were being funded through other utility budgets. This was also done in FY 2013-2014 and FY 2014-2015 with unexpended energy efficiency funds for FY 2012-2013 and FY 2013-2014.

• 73.1% system load factor • Load growth projected at 2.63% for Fiscal Year 2016-2017

Silicon Valley Power Overview Businesses in Santa Clara survived the economic downturn relatively well, and we continued to see load growth during the recession and beyond due to the load that new data centers have been bringing online the last several years. However, even today, most companies are still working with leaner staff and tighter budgets than they did previously, so we are seeing fewer energy efficiency projects due to lack of time and funding. This trend remains in effect, even as the economy has continued to improve. For this reason, we have seen fewer large energy efficiency projects undertaken, but we are beginning to see longer term planning for projects, which are anticipated to be complete in future fiscal years. Silicon Valley Power is unique in its mix of customers. While 85% of the customers are residential, nearly 93% of the utility retail sales are to commercial and industrial customers. Approximately 50% of our electric load is attributable to our largest “Key” Customers. Over 39% comes from data centers. Historically, it is those customers, including the large data centers, who implement a few large projects each year that make up the majority of our energy savings for the year. In Fiscal Year 2015-2016, we saw few of these projects, which is partly due to lack of staff and budget, and partly due to the fact that these customers have been aggressively implementing energy efficiency measures for more than a decade and the opportunities for improvements are fewer and have long payback periods. Some of the energy efficiency measures that are still being implemented include IT improvements, for which SVP does not have an incentive program.

Therefore, while these savings are being achieved in our community, like the energy savings from codes and standards, they are not accounted for in this report. Major Program Changes For FY 2015/2016, Silicon Valley Power added or modified the following programs:

• Residential LED Lighting Rebate – SVP eliminated the mail in rebate and implemented an upstream instant rebate in local stores in conjunction with other Northern California Power Agency (NCPA) member utilities. SVP’s target for the bulbs included in the program were specialty bulbs and those at least 1,000 lumens since there are still few LED options on the market over 1,000 lumens and in certain specialty categories. Incentivizing these bulbs is designed to encourage manufacturers to make more of these bulbs, which have a higher cost due to the additional diodes. This is in line with the Consortium for Energy Efficiency (CEE) recommendations for utility programs across the country.

• Residential Refrigerator Recycling Program: Previously, the incentive was $35 for recycling an old, working refrigerator or freezer. This incentive was increased to $50 to encourage customers to recycle their old refrigerators and freezers through our environmentally responsible recycling provider.

• Residential Pool Pump Rebate: This program provides a $100 rebate to residential customers installing a new variable speed pool pump with a qualifying controller.

• Commercial New Construction Rebate: This program was redesigned and simplified to align with the prescriptive approach to compliance with California’s building energy efficiency code, Title 24. Customers still need to exceed Title 24 by 10% for the measure being incentivized, but rebates are paid at mounts in line with our other prescriptive rebates for retrofit projects. Required paperwork in order to receive the rebate was simplified for customers.

• Enhanced Ventilation Controls Rebate: This program provides an incentive of $160 per ton for adding enhanced ventilation controls to HVAC rooftop packaged units 15 tons or smaller.

• Food Service Equipment Rebate: SVP added two new energy efficiency measures to the program. The CoolerMiser is an occupancy control for reach in coolers with glass doors and was previously the focus of a third party direct install program. As that program ended on June 30, 2015, SVP added a rebate of $100 per unit to the rebate program. SVP also added an incentive of $350 per controlled horsepower for demand controlled kitchen ventilation.

For FY 2015/2016, Silicon Valley Power ended the following programs:

• LEED Rebate: This rebate provided reimbursement to businesses for the cost of registering their LEED building project with the U.S. Green Building Council. Upon completion, if customers met the requirements to obtain LEED certification and achieved the energy requirements, SVP paid a rebate based on the square footage of the facility and the level of certification achieved. SVP ended this program, as there was very little customer

demand for the program of the past several years and no energy savings can be claimed through the program, so it does not contribute to the program goals.

• PC Power Management Rebate: This program provided an incentive for installing qualifying PC Power Management software that demonstrates an annual energy savings of at least 125 kWh. This software is now standard with most new computer purchases and free versions are available for older models. In addition, with “technology refresh” policies averaging between 2-4 years for replacement, the incentive is no longer necessary so the program ended.

• Advanced Lighting Rebate Program: The program provided a $0.20/kWh rebate for advanced lighting controls projects that have such capabilities as real time monitoring and control via remote access and automatic dimming based on occupancy and/or daylighting control strategies, and where the system reduces lighting energy consumption by at least 50%. With the latest version of California Title 24 energy efficiency standard, most of the attributes of an advanced lighting control system are now mandated by code. Therefore, SVP ended this program and rolled lighting controls that achieve savings beyond code into our standard Commercial Lighting Rebate Program.

• Residential Refrigerator Rebates: Previously, SVP provided a rebate on the purchase of a new ENERGY STAR-qualified refrigerator if the old refrigerator was recycled through our program. Due to the increased efficiency of older refrigerators over the past 15 years and very little difference in energy consumption between ENERGY STAR-qualified and non-qualified refrigerators, very little energy savings can be achieved through this incentive program, so it was ended. Funds were redirected to a higher incentive for recycling old appliances, especially secondary appliances that are often the oldest and most unused refrigerators.

• Residential Refrigerator Recycling Program – This program ended when the program implementer, JACO Environmental, went out of business. An RFP was issued for a new program implementer, but no proposals were received so the program ended.

• Low Income Direct Install Program – This program had a first year budget of $200,000 for a direct install program that includes an energy audit, behavior education, and energy efficiency measures at no cost to qualifying customers and is targeted to those customers who average over 800 kWh/month and are on the FRAP program. Funds were not exhausted in the first year, so the program was renewed for a second year. Participation remained low, so the program was ended at the end of the contract term.

Program Highlight In this program year, the customized incentive programs, which includes the Customer Directed Rebate and the Data Center Program, had the largest impact toward our energy efficiency goals. The Customer Directed Rebate program is designed specifically to assist customers with energy efficiency projects that do not fit into our standardized programs. In both the Customer Directed Rebate and the Data Center Program, technical assistance is provided to help customers find customized solutions for their unique situations, and measurement and verification plans are developed and implemented in order to validate the energy savings. These programs require

significant “hands on” approach from SVP, but often result in significant energy savings. This year, a total of 22 custom projects falling under these two programs were implemented for a combined total of 15,284,965 gross kWh in energy savings. Program Descriptions

Res Lighting • Midstream LED Light Bulb Rebates: SVP offers an instant rebate per Energy Star LED bulb

1,000 lumens or greater. • HOA LED Light Bulb Rebates: SVP offers a rebate up to $10 per bulb on qualifying

Energy Star LED light bulbs installed in common areas of Homeowner’s Associations (HOA). Res Pool Pump • Pool Pump Rebate: SVP offers a $100 rebate for the installation of a qualifying variable

speed pool pump and controller. Res Refrigeration • Refrigerator Recycling: Rebate for recycling old refrigerators. (ended mid-program year) Res Cooling • Energy Star Ceiling Fan Rebates: Provides a rebate of $35 per fan (up to three fans per

residence) for the installation of Energy Star ceiling fans.

Res Water Heating • Electric Heat Pump Water Heater: Provides a rebate of up to $1,000 for replacing an

existing electric water heater with an Energy Star Heat Pump Water Heater. Non-Res Lighting • Commercial Lighting Rebates: This program provides rebates for energy efficient lighting

upgrades. Non-Res Cooling • Commercial HVAC Rebate program: This program provides a rebate on the purchase and

installation of new, more efficient air conditioners, HVAC systems, or heat pumps. • Controls Rebate Program: This is a performance-based incentive for controls systems

under a pilot rebate program. The incentive requires demonstrated energy savings over a 5 year period and will make payments annually upon submission of a verification report.

• VFD Rebate: This program provides a rebate on qualifying variable frequency motor drives.

• Enhanced Ventilation Controls Rebate: This program provides an incentive of $160 per ton for adding enhanced ventilation controls to HVAC rooftop packaged units 15 tons or smaller.

Non-Res Cooking & Non Res Refrigeration • Food Service Equipment Rebate: This program provides a rebate for the purchase of

qualifying energy-efficient commercial food service equipment. It includes a variety of equipment, including both cooking and refrigeration equipment.

Non-Res Process • Data Center Efficiency Program*: The program is targeted to data centers with IT server

loads greater than 350 kW or IT cooling loads greater than 100 tons. This program provides unique opportunities for energy-efficiency projects that may not otherwise fit into our standard rebate and customer assistance offerings.

• Uninterruptible Power Supply (UPS) Rebate: This program provides a rebate to customers who install Energy Star UPS equipment to protect enterprise servers, networking equipment, and large storage arrays.

• Plug Load Sensor Rebate: This program provides a rebate for smart power strips used in commercial facilities to reduce energy consumption from office equipment. *Data center projects under these programs may include cooling measures, among others. However, since this is the essential cooling of servers and not for comfort of people, we consider these to be process loads.

Non-Res Comprehensive • New Construction Rebate: This program provides an incentive to customers who exceed

Title 24 by at least 10% on non-residential new construction projects.

Other programs that fall into multiple categories, depending on the energy efficiency measures implemented:

• Public Facilities' Energy Efficiency Program: SVP provides technical assistance and financial incentives for the expansion, remodel, and new construction of City of Santa Clara buildings. Included in this program are higher levels of rebates for qualifying equipment, energy management assistance, and a small budget for retro commissioning.

• City Facilities Energy Efficiency Loan Program: This program provides loans for approved energy efficiency measures implemented at City of Santa Clara facilities. Loans are paid back via the utility bill through the reduction in energy consumption.

• Customer Directed Rebate: This program provides a rebate for energy efficiency projects that do not qualify for our other rebate program offerings, but have demonstrable energy savings.

Other programs educational in nature that do not fall into a category for energy savings:

• Business Audits: Free energy efficiency audits to business customers. • Residential In-Home Energy Audits and Education: Through this technical support program

SVP staff provides on-site audit analysis, energy efficiency recommendations and distributes energy saving items ("lime lite" night lights, outlet gaskets and switch plate thermometers). The Solar Explorer and the SVP information booth participate in major

city events, providing education on energy efficiency and solar electric generation systems.

EM&V Silicon Valley Power’s EM&V plan and reports for the past seven years can be found at http://www.ncpa.com/policy/reports/emv/. For FY 2015-2016 programs, SVP has opted to have its data center efficiency program evaluated by The Cadmus Group. This program was evaluated several years ago and significant changes were made to the program design. Our goal is to determine how well these changes have addressed the issues raised in the original evaluation of the data center efficiency program and further refine the program, if necessary. The report is anticipated to be ready by mid-March 2016 and will be posted with the previous reports on the NCPA website. The EM&V budget averages $75,000 per year, but actual spending varies, depending on the EM&V needs for the year. Sources of Energy Savings Silicon Valley Power uses the POU Technical Reference Manual (TRM) for its energy savings. This can be found at http://cmua.org/energy-efficiency-technical-reference-manual. The lighting calculator used for our commercial lighting rebates can also be found here. The exception to using the TRM is for custom projects, typically funded under our Customer Directed Rebate program, where no deemed values or savings calculators exist in the TRM. For those projects, the customer must submit an M&V plan to be approved by Silicon Valley Power, which may include the use of industry-accepted models or actual pre- and post-measurement data. Complimentary Programs

• Low-Income Programs: Our low income programs include a Rate Assistance Program, where qualified low-income customers receive a 25% discount on their electric bill (low-income program), as well as a Low Income Direct Install Program, which is described in the energy efficiency programs section of this report.

• Renewable Energy Programs:

o Santa Clara Green Power Program: Residents can purchase 100% renewable energy through this voluntary program. The cost for residents and small businesses is a penny and a half per kWh. Larger companies who do not wish to purchase 100% renewable energy may purchase in 1,000 kWh blocks. Block pricing can vary depending on the location of the resources (CA vs. Western U.S), the size of the purchase, and the duration of the purchase commitment.

o Residential Solar Photovoltaic Rebate: Provides significant financial incentive to

residential customers for installation of solar systems. Customers receiving the rebate are required to also complete an energy audit, as is the case with the statewide California Solar Initiative. The rebate started at $4.50 per watt and under a declining scale similar to the California Solar Initiative program, and is currently at $1.25 per watt, up to a maximum system size of 10 kW.


http://cmua.org/energy-efficiency-technical-reference-manual

o Business Solar Photovoltaic Rebate: Provides financial incentives for the installation of solar systems at business sites. Rebate structure is designed to decline over time as more PV is installed in SVP’s service territory, similar to the California Solar Initiative program. Businesses can receive rebates up to a total of $300,000 per customer for systems up to 500 kW. While the rebates started at $3.00 per output watt, current rebate level have declined at the time of this report to $0.65 per watt. Businesses installing systems between 500kW and 1 MW are eligible for a Performance Based Incentive. These incentives started at $0.40 per kWh and are currently at a rebate level of $0.09 per kWh at the time of this report. SVP will stop accepting applications for systems over 50kW after December 31, 2016, but customers have up to one year from the date of application to install a system and performance incentives are paid over five years. Businesses are required to complete an energy audit in order to receive a rebate, as is the case with the statewide California Solar Initiative.

o Neighborhood Solar Program: SVP customers have the option to pay into a special

fund to support the installation of solar electric systems at non-profit community buildings. To date, installations have included PV systems at Haman Elementary School, Valley Village Retirement Community, Bill Wilson Center, Hope Services, St. Justin’s Parish, Our Lady of Peace Church, and the Muslim Community Association (MCA).

• Research, Development, and Demonstration:

o Emerging Technologies Grant: This program encourages businesses to demonstrate new products and product applications not yet commercially viable in today’s marketplace, install energy efficient technologies not generally known or widely accepted, yet show potential for successful market growth, successfully apply energy efficiency solutions in new ways, or introduce energy efficiency into industries or businesses that are resistant to adopting new technologies or practices.

o APPA DEED Program: Silicon Valley Power is a paying member of the American

Public Power Association (APPA) Demonstration of Energy and Efficient Design (DEED) and currently occupies a seat on the DEED Board. This program funds grants, internships and student scholarships to further R&D in the electric utility industry and support innovative applications of energy efficient or renewable technologies. Most recently, in Fiscal Year 2014-2015, SVP applied for and was awarded a DEED grant for a “Field demonstration and performance validation of a CO2 heat pump water heater/space heat combination system” in conjunction with Pacific Northwest National Laboratory. The remainder of the study is funded through Public Benefits Funds under the R&D budget. The study will began in the Fall of 2015 and be complete by May 2017. Silicon Valley Power was also recently awarded two additional grants, both of which have matching funds

coming from the Public Benefits Program. The first is for “Calibrated Modeling of Energy Savings of New High-Efficient Residential Window Covering”. This project will build on the work that the Pacific Northwest National Labs did with Bonneville Power Administration to validate the energy savings of new high-efficient residential window coverings and model the energy savings for the various climate zones so that these results may be considered in energy efficiency program planning across the country. The second project is focused on “Energy Efficient Air Management in Small Data Centers through the Use of Liquid Cooling in Servers”. This project is being conducted in conjunction with University of Washington, which will be modeling, designing and demonstrating a novel cooling solution for data centers. The project’s goal is to implement and prove the enabling of components for the liquid cooling of high heat density Central Processing Units (CPUs) and Graphics Processing Units (GPUs) that will meet the server industry’s requirements for RAS (Reliability, Availability, and Serviceability), cost, and size. Both of these projects are currently in the contract phase.

o California Lighting Technology Center (CLTC): Silicon Valley Power provides

financial support to the CLTC to further research and testing of emerging technologies in the area of lighting.

o Super-Efficient Dryer Initiative (SEDI): Silicon Valley Power provides financial

support to SEDI to further research and testing of emerging technologies in clothes dryers, such as the Energy Star Emerging Technology Award-winning Clothes Dryers, which came on the market within the last three years, and the Heat Pump Clothes Dryer, which became commercially available in the United States in 2015, and holds significant promise for energy savings.

• Electric Vehicles: Silicon Valley Power and the City of Santa Clara have invested in

Electric Vehicle charging stations for public and employee use at multiple City facilities. This includes the following:

Location Level 2 EV Chargers

Level 3 DC Fast Chargers

Central Park Library 1 1 Santa Clara Convention Center 5 1

Tasman Garage (across from Levi's Stadium)

48 1

City Hall 7 0 The purchase or lease of electric vehicles is currently under consideration by our Electric Vehicle Task Force.

• Energy Storage: State Law (Assembly Bill 2514) requires publicly owned utilities to evaluate the use of energy storage as an element of power supply plans by adopting an Energy Storage Procurement Plan. Prior to the City of Santa Clara’s adoption of its plan on August 19, 2014, Silicon Valley Power (SVP), the City of Santa Clara’s electric utility, reviewed various technologies and their relative cost effectiveness in the current marketplace. This review found that storage technologies were not cost effective in 2014 with the exception of large pumped hydro storage, which is very sensitive to particular geographic locations. To satisfy SVP’s obligations under state law, the City Council approved energy storage procurement targets in August 2014. Since that time, SVP staff has continued to meet with vendors and review the cost-effectiveness of energy storage technologies in Santa Clara. Staff put forward an internal strategy regarding demonstration and implementation plan. This implementation plan includes a three pronged effort to study and demonstrate energy storage in a variety of situations in the utility system. On December 20, 2016, Silicon Valley Power submitted an update to the California Energy Commission on its efforts to review and potentially adopt energy storage technologies in its territory. This update provides information on activities by SVP since the 2014 Energy Storage Procurement Plan was adopted and informationally provided to the CEC.

TRINITY PUBLIC UTILITY DISTRICT

Trinity Overview • Created in 1982 as a result of the Trinity River Division Act of 1955, in which Congress

provided mitigation for the economic devastation to the local economy resulting from the Act.

• The Congressional mitigation provides the Trinity River Public Utility District (TPUD) enough low cost and clean hydroelectric power to meet its entire load for the next several decades, but forbids the TPUD from selling any of the energy it does not need to meet load.

• Serves small economically depressed area in northern California consisting of approximately 7,500 meters in mountainous terrain covering an area the size of Delaware.

• TPUD is comprised of nine small substations serving 560 miles of distribution line. • TPUD has a peak coincident demand of approximately 25 megawatts, which may occur in

winter or summer. • More than 60 percent of TPUD’s load is residential and only two customers have a peak

demand of more than 150 kilowatts.

Program Descriptions • Weatherization Program: Provides incentives for installation of cost-effective

weatherization measures including insulation and energy efficient windows in electrically heated homes for all new buildings and major remodels, about 30 per year.

• High Efficiency Heat Pump Rebate Program: Provides incentives to replace wood stoves,

propane furnaces/heaters, and kerosene heating systems with high efficiency electric heat pumps (TPUD’s service territory has no natural gas availability).

• High Efficiency Electric Water Heater Rebate Program: Provides incentives to replace

propane water heaters with high efficiency electric water heaters.

TRUCKEE DONNER PUBLIC UTILITY DISTRICT (TDPUD) Truckee Donner Public Utility District (TDPUD) At a Glance

• Climate Zone: 16 (winter, weekend, and holiday peaking electric utility) • Number of retail customer connections: 13,679 (89% residential) • CY16 total retail sales by customer class (i.e.; residential, commercial, industrial):

$23,015,204 with $12,636,812 residential and $10,378,392 commercial • CY16 total budget for energy efficiency programs (including EM&V, admin/overhead,

incentives): $848,831 • CY16 total amount actually expended for energy efficiency programs: $709,833 (note:

rises to $779,517 when counting expenditures on Electric Vehicle (EV) programs). Truckee Donner Public Utility District (TDPUD) Overview TDPUD serves electricity and water to the greater Truckee area comprised of approximately 44 square miles in eastern Nevada County and approximately 1.5 square miles in adjacent Placer County. TDPUD is governed by a locally elected Board of Directors consisting of 5 members with staggered 4-year terms and operates on a calendar year budget. TDPUD is a transmission-dependent utility within NV Energy’s control area and secures electric resources primarily through the Utah Associated Municipal Power System (UAMPS). TDPUD has been successful in the past in transitioning to renewable energy sources, keeping rates stable, and investing in accessible, cost-effective, energy efficiency programs. In 2016, TDPUD continued to invest in public benefit and electric vehicle programs spending over 4.2% of retail sales including 3.1% of retail sales spent directly on energy efficiency programs. TDPUD’s energy efficiency results included a first year E3 ‘Gross’ energy savings of 1.0% of retail sales, first year E3 ‘Net’ energy savings of 0.7% of retail sales, and TRC of 1.96. TDPUD continues to deliver significant, cost-effective results aided by a customer base that embraces energy efficiency and conservation along with innovative program designs. However, a large portion of current savings come from residential lighting (CFL’s and LED’s) and other lighting programs. Maintaining these saving levels, on paper, is becoming increasingly difficult due, in part, to saturation but mostly due to the dramatic reductions in gross savings due to the miss-application of codes & standards and ‘baseline savings’ to actual energy efficiency retrofits. This is particularly true with screw-in residential lighting (EPA standards) and small business/commercial lighting retrofits (EPA standards & Title 24). TDPUD treats energy efficiency as an electric resource (‘first loading order’) and is therefore motivated by actual savings. However, the E3 model does not consider actual savings and the E3 ‘Gross’ savings are based on codes & standard baselines (not what was actually replaced). Thus, the savings and associated cost-effectiveness from E3 understate the true value of the energy efficiency resource.

Major Program Changes • This is the second year that the EISA (Federal) lighting standards were applied as a

baseline to screw in bulb measures and TDPUD continues to see a dramatic change in associated Residential programs (~37% of our portfolio based on annual kWh savings).

• The E3 ‘Gross’ and ‘Net’ energy efficiency results that the TDPUD is able to claim in this report are diverging further and further away from the actual results. While our performance remains relatively strong, it is getting harder to justify the very high levels of spending based on cost-effective results. Furthermore, the costs and complexity of Title 24 are a major burden for small business/commercial lighting projects which constitutes the vast majority of TDPUD’s commercial customer base. This is causing our customers to either forgo projects, spread them out over multiple years to avoid the Title 24 thresholds, or do the project without pulling permits (and utility incentives).

• TDPUD’s energy efficiency results in the past had a strong commercial lighting component but the savings that we are able to claim continues to drop. The fact is that we still have a significant amount of older lighting technology in our community (T12’s, incandescent, etc.) which could be targeted for cost-effective retrofits but the inability to claim the full, actual savings makes these projects appear to not be cost-effective.

• TDPUD continues to invest in Staff and tools to make the delivery and tracking of our energy efficiency programs easy for the customer and more efficient for the utility. This includes a cloud-based program management tool with on-line rebate applications, improved website, and social media.

• TDPUD continues to invest in our most successful programs and to seek out new, cost-effective program opportunities. TDPUD is seeing strong demand for our point-of-sale LED program, residential LED lighting rebate, refrigerator recycle rebate, appliance rebates which offers increasing incentives for CEE Tiers 2 & 3, and Residential Energy Surveys. Customers have embraced LED lighting technology as shown by a continued increase in LED rebates and a decreased interest CFL’s.

• The funding for the energy efficiency programs increased slightly and spending remains very robust (3.1% of retails sales directly on energy efficiency programs). TDPUD did, in part due to diminishing returns in energy efficiency, move $69,684 into Plug-In Electric Vehicle (PEV) charging stations. The main expenditure was for a grant application to the CEC for DC Fast Charging on the I-80 corridor. Unfortunately, after significant effort and expense to submit the grant to the CEC, the CEC decided to give 100% of the grant funds to private charging networks and failed to give any funds to public-owned electric utilities in the last two grant cycles.

Program Highlight

• TDPUD’s energy efficiency results included a first year E3 ‘Gross’ energy savings of 1.0% of retail sales, first year E3 ‘Net’ energy savings of 0.7% of retail sales, and TRC of 1.96. As stated above, we believe these figures overstate the true cost of the energy efficiency resource. The portfolio performance is solid and overall costs remain at or below TDPUD’s cost to purchase and deliver power.

• TDPUD’s Residential Energy Survey’s remain a very popular program with customers. The ‘visual survey’ comes complete with over 20 free energy and water saving measures – including two free A19 LED bulbs - that are delivered at the end of the survey for free. This program allows customers to implement the ‘low hanging fruit’ immediately and the educational component empowers customers to pursue more complicated energy efficiency opportunities.

• Residential lighting remains a critical program area (TDPUD is 89% residential with a large number of vacation homes). TDPUD continues to effectively deliver residential lighting through our Residential Energy Survey’s, low-income program, at numerous events throughout the community, and at our office. The vast majority of light bulbs delivered to our customers is done face-to-face and the customers must ask for the light bulbs. As stated previously, customers have embraced LED lighting and favor it over the CFL technology.

• TDPUD’s LED Holiday Light Exchange remains very popular with ~3% of our customers visiting the conservation department in less than 1-month. Not only is the program cost-effective and very well received by our customers, but TDPUD takes the face-to-face opportunity to educate customers about other programs and to distribute free residential lighting.

Program Descriptions

• Residential Green Partner Lighting Program (Res Lighting): Encourages customers to replace incandescent and halogen light bulbs with energy efficient lighting by distributing, mostly in person and for free, 7-types of Compact Fluorescents (CFL’s) to customers who visit the TDPUD Conservation Department or at a local event.

EM&V TDPUD operates on a calendar-year for financials and we strive to deliver our completed E3 model and EM&V reports by the March 15th deadline for this report. This is a very short time-frame (2 ½ months) but the alternative of presenting EM&V results more than a year after program completion would not allow for timely feedback and program improvements. It should be noted that, given this timeframe, TDPUD does occasionally make minor adjustments to the E3 model presented in this report and the final results in the EM&V report. TDPUD has been conducting EM&V on an annual basis since 2008 and plans to continue to do so. The budget for EM&V is ~$30,000 per year which is ~4% of program spending. TDPUD’s EM&V reports can be found at http://www.tdpud.org/departments/conservation/em-v-and-reporting.

http://www.tdpud.org/departments/conservation/em-v-and-reporting

Sources of Energy Savings TDPUD used a variety of sources for energy savings estimates including, but not limited to, California Municipal Utilities Association TRM, Pennsylvania TRM, Regional Technical Forum UES, DEER, and utility work papers. TDPUD EM&V reports can be found at (http://www.tdpud.org/departments/conservation/em-v-and-reporting). Complimentary Programs

• Low-Income Programs: The TDPUD’s income-qualified program, Energy Saving Program (ESP), was also described in the Program Descriptions as the participation requires that customers also implement energy efficiency measures. ESP provides a one-time bill credit and a free residential energy survey to income qualified customers. Customers are qualified by an intermediary agency and are eligible for a one-time credit equal to their highest energy charge in the past 12-months (not to exceed $200) upon completion of the required Residential Energy Survey (RES). TDPUD’s income-qualified program achieves a solid return on investment for both the customer and utility.

• Renewable Energy Programs: TDPUD has a successfully fully subscribed our SB1 Solar Rebate program for our customers. TDPUD also achieved an estimated 50% Renewable Portfolio Standard (RPS) in 2016 using the methodology defined by the California Energy Commission. This number would be higher if we considered carbon-free resources. TDPUD has been able to transition our energy resource portfolio from primarily fossil fuel based in 2008 to a diversified mix that includes wind, solar, landfill gas, and small hydro while maintaining stable and competitive rates.

• Research, Development, and Demonstration: It is not practical for a small utility like TDPUD to run direct RD&D programs. However, through the Northern California Power Agency, TDPUD does participate in the American Public Power Associations DEED R&D program, the FLEX lab project and TDPUD Staff does investigate new energy and water conservation products and programs. TDPUD is also exploring public access charging stations for plug-in electric vehicles and is testing an all-electric Toyota Rav4 in our fleet.

• Electric Vehicles: TDPUD installed two Plug-In Electric Vehicle (PEV) public access charging stations locations in 2015. Each location is monetized and has two, Level 2 PEV charging stations and are open to the public. One location is in the Truckee Train Depot in historic downtown Truckee and the other is located in the Pioneer Commerce Center. TDPUD has partnered with the Tahoe Regional Planning Agency (TRPA) on a Truckee-Tahoe PEV Readiness Plan and TRPA received a $200,000 grant from the California Energy Commission (CEC). TDPUD expended significant resources submitting a grant application to the new CEC GFO-15-603 “DC Fast Chargers for California’s Interregional Corridors”. Unfortunately, despite having a grant application that did meet the CEC’s requirements, the CEC did not fund TDPUD and – for the second grant cycle in a row – gave 100% of the awards to private charging networks.

CITY OF UKIAH City of Ukiah At a Glance

• Climate Zone: 2 • Number of retail customer connections: 7,788 • FY15-16 total retail sales by customer class (residential 5,008,108 kWh,

commercial/industrial 9,097,021 kWh) • FY15-16 total budget for energy efficiency programs (including EM&V, admin/overhead,

incentives): $110,000 • FY15-16 total amount actually expended for energy efficiency programs: $92,901

City of Ukiah Overview The City of Ukiah (the City) remains committed to helping their customers manage energy use through energy education and a comprehensive menu of energy efficiency incentives. The City‘s customer base has not typically responded well to a “standard” energy efficiency incentive program. The main reason for this is many customers do not have the discretionary income to fund energy efficiency projects. The City works to overcome this barrier by offering generous incentives to customers to persuade them to participate. However, even with generous incentives, participation in the commercial lighting program was still down in FY2016. Residential and commercial customers enthusiastically participate when the cost of their energy efficiency projects are covered in full by the City’s incentive programs. The City includes seasonal energy saving tips with their customer’s energy bills in order to increase awareness and promote energy education. Major Program Changes For several years, the City’s energy efficiency programs had been operating with a balance forward on a year to year basis. In FY16, that was not the case. In FY16, the balance being carried forward in the PB funds had been expended. Moving forward, rebate amounts and rebate caps were also restructured in attempt to make available funding stretch to serve more customers and more projects. The result is that customer co-pay requirements increased which reduced participation in Ukiah’s EE programs. In FY16, EE programs acquired 112,854 kWhs, or 25% the adopted 448,000kWh energy efficiency goals. Since FY11, the City has acquired 145% of the adopted energy efficiency targets. Program Highlight The Commercial Lighting Program delivered the greatest percentage of savings in FY16, accounting for 86% of the total savings. The City has worked diligently over the years to build a network of lighting contractors and strived to keep them engaged in the program. Program Descriptions The City manages a comprehensive energy efficiency incentive program for residential and commercial customers focusing on energy efficiency and peak load reduction. For residential customers, rebates are offered for the installation of various energy efficiency measures, such as

lighting, HVAC, appliances, and weatherization. For commercial customers, rebates are available for upgraded lighting, HVAC, appliances, refrigeration equipment, electronics, and in cases where an analysis is performed rebates can be offered for additional equipment that reduces energy use and/or demand. On-site energy audits are provided by the City energy specialists. Energy efficiency measures are recommended and additional visits are completed upon request.

• Residential Lighting [Res Lighting]: The City offers rebates to homeowners who install ENERGY STAR® qualified LED lamps/bulbs, ceiling fans and LED holiday lights.

• Residential HVAC [Res Cooling]: The City offers rebates to homeowners who install high performance heat pumps and air-conditioners, or evaporative coolers that exceed current state requirements. The City also offers a rebate for duct sealing when not required by code.

• Residential Equipment [Res Clothes Washers; Res Dishwashers; Res Pool Pump; Res Refrigeration; Res Electronics]: The City offers rebates to homeowners who purchase new ENERGY STAR qualified products, including clothes washers, dishwashers, pool pumps, refrigerators and advanced power strips. Rebates are also available for refrigerator and freezer recycling.

• Residential Weatherization [Res Shell]: The City offers rebates to homeowners who invest in weatherizing their homes, including attic and wall insulation, window treatments/replacement, solar attic fans, and air sealing.

• Residential Water Heater Rebate [Res Water Heating]: The City offers rebates to homeowners who purchase a new, energy efficient electric water heater.

• Commercial Lighting [Non-Res Lighting]: The City offers rebates to business owners who invest in the installation of energy efficiency lighting upgrades. There is a prevalence of inefficient lighting throughout the city instead of more efficiency fluorescent or LED fixtures.

• Commercial Custom [Non-Res Comprehensive]: The City offers rebates to business owners based on site-specific consumption. Rebates are tailored to the individual business owner’s needs based on the audit and the potential energy savings associated with the customer project.

EM&V The City has budgeted $5,000 in FY2017 for evaluation of our programs. The City is currently exploring the opportunity of partnering with a group of other NCPA utilities on this EM&V effort to gain economies of scale. Sources of Energy Savings For FY16, the City has relied heavily on the savings listed in the Technical Resource Manual. The Commercial Lighting and Commercial Custom programs use custom savings calculations. Complimentary Programs

• Low-Income Programs: The City offers a low-income bill assistance program to eligible customers

• Renewable Energy Programs: The City currently offers a Solar Photovoltaic rebate program as described in SB1 legislation. The City is evaluating what, if any solar PV programs will be offered after the SB1 legislation expired on December 31, 2016.

Reliable Power In April of 2016, Vernon Gas & Electric was awarded the prestigious Diamond Level designation of Reliable Public Power Provider (RP3) from the American Public Power Association (APPA). VG&E earned this accolade by providing exceptionally reliable and safe electric service. The department compiled a 1400 page submission that was scrutinized by industry experts. The RP3 distinction recognizes public power utilities that demonstrate proficiency in four key disciplines: reliability, safety, workforce development, and system improvement. VG&E is one of just 8 utilities among over 2,000 public power utilities in the U.S. achieving Diamond level recognition for this 3 year period. Vernon Gas & Electric ranks in the top 10% for electric system reliability in the US according to a nation-wide benchmarking study that utility participates in annually. VG&E serves essential and dependable gas, electric and fiber resources to the City’s business community at very competitive rates in comparison to neighboring utility providers. The City owned and operated utility systems has a well established, strong, history of reliability, capable of efficiently and serving the needs of the City’s unique business community.

Integrated Resource Plan VG&E utilizes an Integrated Resource Plan (IRP) to identify, evaluate and procure its power supply needs. The goal of the IRP is to provide a long term strategy to meet the Vernon’s future electric needs. As such, the plan designates the amount, timing, and type of resources that achieve this goal in accordance with applicable the standards, while reducing greenhouse gas emission standards. These challenges must be met while safeguarding energy costs affordable to retail customers. The plan provides information associated with resource acquisitions to meet the future electricity demand of the customer base, including capacity and energy supply resources, renewable energy and demand side management. In this context, VG&E’s power system and compliance with regulatory and legislative mandates:

• Provides reliable and affordable energy to ratepayers; • Maintains compliance with all laws and regulations governing VG&E and pertinent

business activities; • Continues to pursue and implement energy efficiency and demand side management

programs that are cost effective and achieve demand reduction. • Reduces greenhouse gas emissions to fully comply with California law as enacted by

Senate Bill 350, “the Clean Energy and Pollution Reduction Act of 2015” (SB 350), which mandates Greenhouse Gas (GHG) emissions reduction in California of 40 percent from 1990 by 2030;

• Increase the amount of qualifying renewable energy resources in its power supply portfolio to 50% of total energy by 2030.

VG&E has acquired multi-year contracts for solar and landfill gas power generation to satisfy the RPS requirement as required by the State of California and Senate Bill X1 2. With the addition of these resources, the proportion of the overall portfolio supplied by bundled renewable energy will enable the City to attain an RPS of 33% by 2020, as required by Senate Bill x1 2. VG&E will continue to procure additional resource to meet Vernon’s long-term goal of reaching an RPS of 50% by 2030 as required by Senate Bill 350.

ALAMEDA MUNICIPAL POWER Alameda Municipal Power 10-Year Energy Efficiency (EE) Potential Studies – At a Glance

• 2018-2027 Average Annual Target: 0.28% of forecasted retail sales. • The annual targets are reported as NET savings. • Energy savings from future updates to Title 24 Building Energy Efficiency Standards are NOT

included in the annual targets • The baseline for measures is EXISTING CONDITIONS for non-residential projects that require

pre-install and post-install inspections and CODE for residential measures. Navigant used their Electric Resource Assessment Model (ELRAM) to estimate achievable energy and demand savings over a 10-year forecast period. The modeling team forecasted these savings using two modeling steps:

1. Base Case Run. This modeling run includes no changes or adjustments to Alameda’s current portfolio of energy efficiency programs.

2. Final Run. Alameda’s Final Run included the following adjustments to their Base Case Run:

• Expanded measure list. Navigant modeled a number of measures to provide a picture of potential savings should Alameda decide to expand their current programs. After review, Alameda expanded the reach of the Energy Plus non-residential program.

Table 1. Inputs to Figure 1

Comparison to 2014-2023 10-Year EE Potential Studies Impact of Renewable Energy Credit Sales AMP has benefitted from an infusion of program funding due to the short-term sale of AMP’s renewable energy credits (REC) in 2012-2016. The proceeds from the REC sales, as well as a smaller amount of funds from the state’s Cap and Trade program, have been used, at the direction of AMP’s Public Utilities Board (PUB), solely for greenhouse-gas (GHG) reduction projects. These new funds were used for several short-term or one-time programs that created a wealth of savings for program years 2015 and 2016. As a result, AMP exceeded the targets—which were set in 2013—by 217 percent in 2015 and 362 percent in 2016. AMP expects to have some REC-sales funding available through 2019. The 10-year targets reflect the expected reduction in funding and saturation in the lighting sector, with a decrease in savings. The short-term infusion of program funds has effectively front-loaded energy savings to the 2015-2019 program years. Table 1 reviews program years 2014 to 2023 - the targets set in 2013 and the new targets set today. Actual savings for 2014, 2015 and 2016 are shown in the 2017 Targets column.

10 Year Energy Goals (Net MWh)

10 Year Demand Goals (kW)

Residential Sector AMP’s average residential customers have reduced their energy use by 3 percent per year since 2012, and we expect this trend to continue. Alameda has a very mild climate and few homes have air conditioning. While appliance standards (Title 20) and building codes (Title 24) have certainly contributed to a more energy-efficient home in Alameda, AMP’s residential programs have also helped. For example, proceeds from the REC sales were used to send two LED light bulbs to every residential customer in 2015. This program contributed to 2015 savings that exceeded the target, but it also meant that two sockets per home would be unavailable for future programs. Fortunately, the savings from LEDs persist for 15 years. New savings opportunities, however, are becoming more limited. The classic Energy Star refrigerator recycling program has historically comprised 80 percent of AMP’s residential savings (excluding Opower’s behavior change program and the LED promotion). The 2016 Technical Resource Manual (TRM) halves the claimed energy savings from refrigerator recycling as of January 2017. This reduction will, understandably, lower AMP’s residential expected savings and future-looking targets. AMP will continue to offer our award-winning online rebate program for refrigerators, freezers, LED bulbs, LED fixtures, LED decorative string lights, washing machines for all-electric homes, electric dryers, and electric heat pump water heaters. The residential neighbor comparison and behavior-change program, “My Energy,” run by Opower, was a major source of annual savings. The program, which was funded by AMP’s participation in the state’s Cap and Trade program, was in effect from October 2012 through 2016. In 2016, My Energy had the highest net annual energy savings of AMP’s entire energy-efficiency portfolio. The program’s Total

Resource Cost (TRC) was among the lowest in AMP’s offerings at 0.7, and savings only persist for one year. Despite the annual savings, the program was very expensive and only benefited the half of the residents that received the five-times-a-year paper report. The program concluded in December 2016. Non-Residential Sector Since 2015, Alameda’s non-residential customers have benefitted from direct-install energy-efficiency programs. The goal of the direct-install programs is to reduce customer barriers such as knowledge of technologies, funding for staff to manage projects, fair pricing and protection from unscrupulous contractors, quality equipment/installations and first costs. These programs are funded through REC sales. AMP’s REC-funded “Commercial Lighting Program” was available from October 2014 through December 2015. More than 70 percent of the program participants were small businesses who had never before participated in a program. Over 90 percent of the installed measures were LEDs. Based on the success of that program, AMP started the “Energy Plus Program” to include all non-residential customers and refrigeration measures. This program was launched in January 2016 and will conclude in December 2017, with expected energy savings of over 3,000 MWh. The majority—over 60 percent—of streetlights were converted to LEDs in program year 2016. Conclusions The targets after 2019 are low both due to of the unavailability of REC funds and because we expect to be close to market saturation in some sectors and end uses, notably residential lighting and non-residential exterior lighting. The impact of codes and standards such as Titles 20 and 24, and California policies such as AB 758 and SB 350 are unknown. The 2017 targets are based on current cost-effective energy-efficiency measures. When this target exercise is repeated in 202, future targets may be revised higher or lower depending on the political climate; associated national, state, and local policies; and pending litigation regarding Proposition 26. At a local level, it is unclear how AMP’s new solar rate, the Energy Renewable Generation (ERG) plan, will impact customer demand for solar installs compared to Net Energy Metering (NEM). ERG is seen by the solar industry as less lucrative than NEM. Residential and commercial customers alike may opt to reduce their use (bills) via energy efficiency rather than solar – or they will just install increasingly larger photovoltaic systems and completely ignore efficiency opportunities. AMP’s energy-efficiency portfolio is heavily reliant on lighting measures. When an LED-retrofit fixture with wireless sensors is widely feasible and a cost-effective retrofit for existing fluorescent tubular fixtures, the targets will change considerably. Current iterations of the LED technology, particularly those compliant with Title 24 sensor requirements, have a long payback period and are not appropriate for all applications. When a solution is available on the market with a payback of less than three years, AMP expects to see an increase in market potential savings. On the residential side, AMP will be watching for fuel-switching opportunities, potentially associated with SB 350. Residential potential today does not include HVAC since there is no air conditioning load. If residents are encouraged to complete building

envelope upgrades and consider moving to a heat pump, Alameda as a whole would see a reduction in total energy consumption, and the associated GHG.

Comparison to 2014-2023 10-Year EE Potential Studies Glendale’s estimate achievable energy and demand savings over a 10-year forecast period is based on the California Municipal Utilities Association’s (CMUA) Energy Efficiency Potential Forecasting Study conducted by Navigant Consulting, Inc. in 2016 using the Electric Resource Assessment Model (ELRAM). Glendale’s total annual MWh savings target from the 2016 model is 130,474 MWh, an increase of 8.0% from the 2013 model of 120,780 MWh. In the 2016 model, Glendale’s total incremental potential as a % of total sales for the first four years from 2018 through 2021, shows an average of 1.31% whereas in the 2013 model from 2014 through 2017 it was at an average of 1.04%. The average 10 year annual target from 2014-2023 model at an average of 1.07% compared to the current 10 year annual target from 2018-2027 at an average of 1.16%. The primary reason for the higher energy savings goals in this current 2016 study is attributed to the claim of Codes and Standards savings. To help support the increase in our annual energy savings targets we are planning on expanding our Conservation Voltage Reduction (CVR) pilot program. One of the major benefits of Glendale Water & Power’s (GWP) investment in utility modernization is its ability to use the data generated by the digital meters to reduce power costs by increasing the efficiency of GWP’s distribution system. An effective CVR program is one way to do just that. Our goal is to save energy by improving feeder voltage efficiency and reaping the benefits of our Advanced Meter Reading Infrastructure (AMI).

CITY OF GRIDLEY City of Gridley 10-Year EE Potential Studies – At a Glance


included in the annual targets. • The baseline for measures is code for deemed measures, and existing conditions for the non-

residential lighting and custom programs. Navigant used their Electric Resource Assessment Model (ELRAM) to estimate achievable energy and demand savings over a 10-year forecast period. The modeling team forecasted these savings using two modeling steps:

1. Base Case Run. This modeling run includes no changes or adjustments to Gridley’s current portfolio of energy efficiency programs.

2. Final Run. Gridley chose to call their Base Case Run as Final and made no adjustments to modeling scenarios.



Comparison to 2014-2023 10-Year EE Potential Studies Gridley Municipal Utility (GMU) relied on the ELRAM model to determine the EE potential in the upcoming ten-year period. The current ELRAM model reflected a 38% reduction in potential for 2018-2023. GMU feels a significant responsibility to its community to invest their Public Benefits funds in such a way as to impact both energy savings and financial savings/positive economics in Gridley. GMU offers a comprehensive menu of rebates to all of our customers. GMU’s customer demographic has historically resulted in lower customer participation in programs that require capital investment by the customer.






HEALDSBURG ELECTRIC DEPARTMENT Healdsburg Electric Department 10-Year EE Potential Studies – At a Glance


included in the annual targets. • The baseline for measures is existing conditions, except for select measures.


1. Base Case Run. This modeling run includes no changes or adjustments to Healdsburg’s current portfolio of energy efficiency programs.

2. Final Run. Healdsburg’s Final Run included the following adjustments to their Base Case Run:

• Utilized a 3-year average calibration target. The three-year average of the years 2013 through 2015 is 32% higher than the 2015 program achievements.

• Expanded measure list. Navigant modeled a number of measures—not currently offered in Healdsburg’s portfolio—to provide a picture of potential savings should Healdsburg decide to expand their current programs. Healdsburg added several residential and commercial measures.

• Increased promotional costs by 50%. • Increased incentive by 50%.








Comparison to 2014-2023 10-Year EE Potential Studies The City of Healdsburg did not see significant changes from the annual targets adopted in 2013 for 2018-2023 in the energy efficiency potential studies. There continues to be opportunity for energy efficiency savings in residential, commercial, and industrial sectors in the near term. Looking toward the end of the 10-year window, if program offerings remain the same, savings will dwindle. It will be important to focus on adjusting, revitalizing, and adding new programs as current programs reach saturation. While more than 80% of the City’s electric customers are residential, 66% of retail sales are commercial and industrial customers. This means that, while residential programs, education and outreach will remain a large part of the City’s energy efficiency catalogue, the biggest opportunity for savings will continue to come from commercial and industrial projects. The City is, and will continue to be, focused on growing program offerings to these customer segments that include assistance identifying and completing energy efficiency improvements.

LOS ANGELES DEPARTMENT OF WATER AND POWER (DWP) Los Angeles Department of Water and Power (DWP) 10-Year EE Potential Studies – At a Glance

• A FY17-18 through FY26-27 average annual target of 1.50% of forecasted retail sales. • Gross savings targets of 15% between FY17-18 through FY 26-27. • LADWP claims gross C&S savings. • A/C Optimization Program added in FY20-21. • Efficient Product Marketplace Program added in FY20-21. • Commercial Direct Install Program added in FY20-21. • Added additional measures to existing programs starting FY20-21. • Residential Behavioral Programs expanded in FY20-21. • Commercial and Industrial Behavioral Programs added in FY20-21. • Incentives increased by 1.5 starting in FY20-21. • The C&S claim is expressed as GROSS savings • All measures are using existing condition baselines when savings are available in that format,

staying consistent with how LADWP programs are administered. Any potential double counting of C&S savings have been taken into consideration and removed from the C&S potentials.

Summary of Potential Navigant used their Electric Resource Assessment Model (ELRAM) to estimate achievable energy and demand savings over a 10-year forecast period. The modeling team forecasted these savings using two modeling steps:

1. Base Case Run. This modeling run includes no changes or adjustments to LADWP’s current portfolio of energy efficiency programs.

2. Final Run. This modeling run uses LADWP’s chosen adjustments—if any—to various features within the model to illustrate increased energy savings goals. This run may be the same as the Base Case Run if the utility chose not to make adjustments to current portfolio offerings

LADWP’s Final Run included the following adjustments to their Base Case Run:

• LADWP, from a recent, different potential study, had in place program goals through FY19-20. These goals were maintained.

• A/C Optimization Program added in FY20-21 • Efficient Product Marketplace Program added in FY20-21 • Commercial Direct Install Program added in FY20-21 • Added additional measures to existing programs starting FY20-21 • Residential Behavioral Programs expanded in FY20-21 • Commercial and Industrial Behavioral Programs added in FY20-21 • Incentives increased by 1.5 starting in FY20-21

• Promotional administrative costs increased by 2.0 starting in FY20-21


The results of this potential study are subject to LADWP Board approval, currently scheduled during summer of 2017. As a result, the details may potentially change, at which time LADWP will notify the CEC of any such discrepancies from this report


Comparison to 2014-2023 10-Year EE Potential Studies LADWP’s current goals are significantly higher compared to the projections established in the prior study for the same timeframe between FY20-21 through FY26-27. There are several reasons for these higher projections:

• A/C Optimization Program added in FY20-21 • Efficient Product Marketplace Program added in FY20-21 • Commercial Direct Install Program added in FY20-21 • Added additional measures to existing programs starting FY20-21 • Residential Behavioral Programs expanded in FY20-21 • Commercial and Industrial Behavioral Programs added in FY20-21 • Incentives increased by 1.5 starting in FY20-21 • Promotional administrative costs increased by 2.0 starting in FY20-21 • Elimination of economic screening that is overwritten by incentive rates and incentive caps that

allows for natural elimination of measures that are not cost effective to the customer.

LASSEN MUNICIPAL UTILITY DISTRICT Lassen MUD 10-Year EE Potential Studies – At a Glance


included in the annual targets. • The baseline for measures is code for deemed measures, except for non-residential lighting and

custom projects which use existing conditions. Navigant used their Electric Resource Assessment Model (ELRAM) to estimate achievable energy and demand savings over a 10-year forecast period. The modeling team forecasted these savings using two modeling steps:

1. Base Case Run. This modeling run includes no changes or adjustments to Lassen’s current portfolio of energy efficiency programs.

2. Final Run. Lassen modified program design to include early retirement starting in 2018.



Comparison to 2014-2023 10-Year EE Potential Studies In the past few years Lassen has experienced very small to nearly flat load growth in all customer sectors. This has a negative effect on potential energy efficiency opportunities. Within the next few years we anticipate the lighting market will be saturated with LEDs which have historically made up a large percentage of our savings. We plan on exploring new technologies as they come into the market place to augment our existing programs in order to achieve our EE goals. For years 2018-2023, our 2018-2027 goals are 2% higher than the prior study, which is in line with our anticipated load growth in the same time period. Based on the ELRAM model, we believe our EE goals are reasonable and achievable.

CITY OF LOMPOC City of Lompoc 10-Year EE Potential Studies – At a Glance

• 2018-2027 Average Annual Target: .20% of forecasted retail sales. • The annual targets are reported as GROSS savings. • Energy savings from future updates to Title 24 Building Energy Efficiency Standards are NOT

included in the annual targets. • The baseline for measures is existing conditions, except for select measures.

The climate and customer mix of Lompoc limit opportunities for energy savings potential. Due to the mild climate year round, air conditioning is not typically installed in residential buildings and is limited in commercial buildings. Heating is done primarily with gas. The average residential electric consumption per month is 325 kWh. The peak demand for electricity is in the winter in the early evening. Since there is little need for air conditioning in our coastal climate and heating is primarily done with gas, the majority of rebate programs are focused on lighting and refrigeration retrofits. Commercial customers make up 11% of the customer mix. Municipal use makes up 1%. Of the 88% of residential customers, 56% live in rental housing and 21% of these are at or below the poverty level (taken from 2011-2015 American Community Survey). Lompoc is considered a disadvantaged community and a very small portion of residential customers have the expendable money to upgrade to more energy efficient equipment unless Lompoc heavily subsidies the purchase of the equipment. Hence, Lompoc has created programs that offer a higher rebate and pays for the initial purchase of a product with the customer paying back a portion over a one year period. The majority of Lompoc’s commercial customers are small business owners who rent on a short term lease, have relatively low electric bills and are often unwilling to perform retrofits to the building. Lompoc has no industrial customers and limited demand customers. Since there is little need for air conditioning in our coastal climate, most of our rebate programs are focused on lighting retrofits. Many customers have already retrofitted T-12 lighting to T-8 and hesitate or are unable to expend available monies on greater energy efficiency savings with LED lighting. The increased building code requirements and Title 24 Standards have also discouraged customers from upgrading due to the increased costs. Most of the larger commercial customers or demand customers who have long term leases or own their building have taken advantage of lighting retrofits and efficiency programs in the past. We have little manufacturing facilities in the City and the few we have are small and do not have the potential for upgraded equipment. Therefore, it is becoming more and more difficult to offer energy efficient incentives and achieve and meet goals but staff will continue to look at potential programs that will be attractive to our customers while striving to meet our energy efficiency goals. To encourage more participation in programs, Lompoc will consider providing more direct install programs to make it easier for customers. In the commercial sector, the restaurant market has potential for energy savings through appliance and refrigeration cooler retrofit programs. Small convenience and

grocery stores may see additional savings through refrigeration case lighting, equipment and gasket rebate programs. The City will evaluate the addition of commercial direct install incentive programs for lighting and refrigeration to encourage tenants to make retrofits with less out of pocket costs. In the residential market, an upstream LED light bulb program will be considered to make it easier for customers to purchase LED lighting without having to exchange bulbs as required by the current program. Many customers took advantage of previous CFL rebate programs and are unwilling to invest in new LED lighting. To help the few customers with all electric homes, rebates will be provided to customers retrofitting old appliances heated by electricity to more efficient electric or gas appliances. Staff will also consider creating new direct install programs for interior and exterior lighting, refrigeration and electric water heating to encourage owners of multi-family buildings to invest in energy efficiency.



Comparison to 2014-2023 10-Year EE Potential Study For years 2018-2023, Lompoc’s current 10-year goals are higher than the goals established in the prior study. The primary reasons for the higher savings include adding residential and commercial sector

measures to the portfolio, starting in 2018 and claiming gross savings targets while net savings targets were claimed in the prior study. The climate and customer mix of Lompoc limit opportunities for energy savings. Commercial and municipal customers make up only 12% of the customer base while 88% of the customer base is residential. Due to the mild climate year round, air conditioning is not typically installed in residential buildings and is limited in commercial buildings. Since there is little need for air conditioning and heating is primarily done with gas, the majority of rebate programs are focused on lighting and refrigeration retrofits. Saturation of these markets will be seen in the next few years. To increase savings potential, several measures will be added to the portfolio, mostly in the commercial sector. To encourage more participation, Lompoc will evaluate adding new direct install programs in both the commercial and residential sectors to make it easier for customers to invest in energy efficiency upgrades.

Comparison to 2014-2023 10-Year EE Potential Studies For years 2018-2023, Merced’s current 10-year goals are about 79% of the goals established in the prior study. The Merced Irrigation District (MID) provides retail electric service to over 9,000 customers, approximately 7,500 residential customers and 1,500 commercial/industrial customer in Eastern Merced County. The District has been providing retail electric service since 1996. Our residential rate base is primarily made up of new construction. While we offer customers rebates for appliances, air conditioning, and lighting, we have very little claimed energy savings from our residential customers. A majority of MID’s energy efficiency savings result from projects from our larger industrial customers. These customers implement larger energy efficiency projects. Our future goals include a complete overhaul of our current rebate programs. We will be updating our current rebates to be more in line with current industry applications. In addition to revising the current types of measures, we will also evaluate increasing incentive amounts. Another possibility is to add behavioral programs. Additional marketing and promotion for new programs will also be needed. New programs will produce the need for customer education and allow for additional marketing efforts.

2. Final Run. Modesto chose to call their Base Case Run as Final and made no adjustments to modeling scenarios.



Comparison to 2014-2023 10-Year EE Potential Study The current EE potential study is based on an enhanced version of the modeling tool used for the previous EE potential study. The enhancements made to the modeling tool since the prior EE potential study are described in detail elsewhere in this 2017 POU status report. However, one key factor - model calibration - resulted in a significant change (downward adjustment) to MID’s targets for the current study relative to the previous study. Over the past decade, MID’s annual EE program results have fluctuated greatly from year to year, ranging from a low of 5.6 GWH to a high of 16.8 GWH (0.22% of actual sales to 0.69% of actual sales). For the 2014-2023 study, model calibration was set at 1% of forecasted sales, which was significantly higher than MID had ever achieved. For the 2018-2027 study, model calibration was set at the average of the prior three years of program achievement, which included two moderate years and one higher year. As such, model calibration for the current study is not unduly influenced by an outlier or arbitrary value as model calibration for the previous study may have been. The revised model calibration methodology reflects continuation of MID’s current program offerings and results in targets that better align with actuals. MID regards the model output to be representative of the incremental market potential for its anticipated EE programs. MID has not yet formally adopted EE targets for the 2018-2027 forecast period, so this data is provided as preliminary and subject to possible revision.

Sum of 10-year EE Goal 8.5% 82,300

Comparison to 2014-2023 10-Year EE Potential Studies The City of Palo Alto Utilities (CPAU) has long recognized cost-effective energy efficiency (EE) as the highest priority energy resource, given that EE typically displaces relatively expensive electricity generation, lowers energy bills for customers, and contributes to economic development. Relative to the 2014-2023 annual savings goals these new annual savings goals for 2018 to 2027 are 35% higher as shown in Figure 1. On a cumulative basis, the 2018-2027 cumulative electric EE goal of 5.7% is 19% greater than the cumulative goal of 4.8% from 2014 to 2023 as shown in Figure 3. These goals are especially ambitious given 1) savings from lighting are expected to decline, due to our high penetration of LED lighting, and 2) that CPAU does not claim savings from increasingly stringent statewide building codes and appliance standards. CPAU is proposing to test and evaluate a number of new programs to reach these ambitious goals. As the increase in annual savings targets is larger than the increase in cumulative savings, this also represents a general shift in the portfolio towards relatively shorter-lived savings such as behavioral savings and retrocommissioning (RCx) measures.

Figure 1. Comparison of 2018-2027 electric EE goals to 2014-2023 electric EE goals.

Figure 2 shows the reported EE savings as well as the 2018-2027 annual electric EE goals expressed in MWh. The big jump in 2012’s reported savings was due to the completion of a significant EE project at a large commercial site, which is unlikely to be replicable. Figure 2. Historic electric EE savings and 2018-2027 annual electric EE goals on an energy basis.

The projected cumulative savings from these goals is shown in Figure 3. The cumulative savings from 2018 to 2027 attributable to utility programs, without counting statewide building codes and appliance standards, is projected to be 5.7%. The cumulative savings from 2018 to 2027, including both utility programs and statewide building codes and appliance standards, is projected to be 8.5%.

Figure 3. Projected cumulative electric EE savings from 2018-2027, not including cumulative savings prior to 2018.

New programs and programs changes modeled using Navigant ELRAM model CPAU used the Navigant ELRAM model to explore new programs that would significantly increase our EE market potential beyond our existing EE portfolio. Under a Business-As-Usual scenario with no new programs, the ELRAM model estimates a market potential with average annual savings of 0.65% and cumulative savings of 4.9% from 2018 to 2027. Under an aggressive EE scenario which includes several new programs, the ELRAM model shows a CPAU market potential with average annual savings of 0.85% and cumulative savings of 5.7% from 2018 to 2027. CPAU adopted the 2018-2027 goals shown here based on this aggressive EE scenario. The following three new programs are primarily responsible for the increased market potential of EE savings, as they are projected to provide substantial new streams of highly cost-effective savings.

1. Requiring retrocommissioning (RCx) activities to follow the 2016 Statewide Retrocommissioning Policy & Procedures Manual regarding procedures to ensure longer persistence of RCx savings.1

Currently CPAU assumes that RCx savings have a one-year persistence; in other words, RCx projects do not result in EE savings after one year. The statewide manual for the investor-owned utilities recommends greater persistence of RCx savings, but specifies policies to ensure this persistence. CPAU will be implementing these procedures outlined in the manual in order to ensure persistence of RCx savings.

2. Building Operator Certification (BOC) program savings based on the 2014 study2 funded by the California Public Utilities Commission (CPUC)

1This manual governs the RCx procedures for investor-owned utilities. The protocols CPAU will be implementing are shown in the project persistence section 1.7 of the 2016 Statewide Retrocommissioning Policy & Procedures Manual found here: https://www.pge.com/pge_global/common/pdfs/save-energy-money/facility-improvements/retrocommissioning/2016-Statewide-RCx-Policy-Procedures-Manual.pdf

https://www.pge.com/pge_global/common/pdfs/save-energy-money/facility-improvements/retrocommissioning/2016-Statewide-RCx-Policy-Procedures-Manual.pdf

https://www.pge.com/pge_global/common/pdfs/save-energy-money/facility-improvements/retrocommissioning/2016-Statewide-RCx-Policy-Procedures-Manual.pdf

In 2014 a study funded by the CPUC found net savings of 32.02 MWh, 0.0045 MW, and 0.525 kTherm per participant from the BOC program in California. These savings are calculated using a net to gross ratio of 0.69. This same study suggests that persistence of the BOC program savings can be conservatively estimated at three to four years. CPAU is evaluating the appropriate accounting for the BOC training as well as the appropriate persistence of energy savings.

3. Accounting for the Palo Alto Energy Reach Code savings from the Green Building Ordinance.

To date, the Palo Alto local energy reach code savings have not been claimed despite modeling that suggests substantial savings. CPAU will be developing a process to capture the energy savings attributable to the local Green Building Ordinance. Modeled end-use savings will then be associated with the appropriate persistence as well as the appropriate compliance factors. Preliminary analysis suggests large potential savings from the current energy reach code, and future code cycles may capture more cost-effective savings from existing buildings.

The three programs detailed above are the highest priority new programs, with other programs focusing on early retirement protocols for select measures. CPAU will also be evaluating new programs in residential behavioral savings, financing, and emerging EE technologies. CPAU will be continuously monitoring the cost-effectiveness of programs as CPAU incentives are substantial and CPAU marketing efforts are already extensive. Projected Demand Savings Based on the aggressive EE scenario the ELRAM model projects the electric EE demand savings shown below in Table 2 for CPAU. Table 2. Projected electric demand savings from the CPAU 2018-2027 electric EE goals.

PASADENA WATER AND POWER Utility Name 10-Year EE Potential Studies – At a Glance

• 2018-2027 Average Annual Target: 1.25% of forecasted retail sales. • The annual targets are reported as GROSS savings. • Energy savings from future updates to Title 24 Building Energy Efficiency Standards ARE included

in the annual targets. • The baseline for measures is a mix of existing condition and code baselines for modeled

measures, as well as a “dual baseline” function. Navigant used their Electric Resource Assessment Model (ELRAM) to estimate achievable energy and demand savings over a 10-year forecast period. The modeling team forecasted these savings using two modeling steps:

1. Base Case Run. This modeling run includes no changes or adjustments to Pasadena’s current portfolio of energy efficiency programs.

2. Final Run. Pasadena chose to call their Base Case Run as Final and made no adjustments to modeling scenarios.

Comparison to 2014-2023 10-Year EE Potential Studies Compared to Pasadena Potential Study results for 2014-2023, the updated potential model shows more savings opportunities available, primarily due to the inclusion of Code and Standards as well as a result of new emerging technologies. The model also demonstrated a significant decline in potential beginning around 2022 due to a forecast of there being fewer savings opportunities remaining within the commercial building stock and diminishing savings from adopted Codes and Standards. Staff developed the proposed ten-year energy efficiency and demand reduction goals based on the model results, but also with consideration for simplicity of the goals, the City’s environmental objectives, historical goals and achievements, and what may be practically achievable based on past experience. PWP is planning to adopt a goal of 13,500 MWh per year over the 2018 – 2017 or 1.25% of forecast retail sales. PWP is proposing to continue maintain the demand reduction goal of 2.3 MW established in 2013, based on historical program achievements over the last five years.

2. Final Run. Pittsburg’s Final Run included the following adjustments to their Base Case Run:

• Expanded measure list. Navigant modeled a number of measures—not currently offered in Pittsburg’s portfolio—to provide a picture of potential savings should Pittsburg decide to expand their current programs. Pittsburg added some residential and non-residential measures to their programs.

Comparison to 2014-2023 10-Year EE Potential Studies With high penetration of residential roof-top solar (10% of total residential load) and potential solar installation of a few big commercial electric users on Mare Island, it has become more challenging to adopt new energy efficiency programs with satisfactory results. The Commercial Lighting Program has been the most in-demand energy efficiency programs on Mare Island. The program has been implemented for 7 years and many large commercial customers and government agencies have benefited from the program. With LED lights becoming more affordable, we anticipate that the program will remain popular in the next few years.

CODE. Navigant used their Electric Resource Assessment Model (ELRAM) to estimate achievable energy and demand savings over a 10-year forecast period. The modeling team forecasted these savings using two modeling steps:

1. Base Case Run. The Base Case modeling run includes no changes or adjustments to Port of Oakland’s current portfolio of energy efficiency programs.

2. Final Run. Port of Oakland’s Final Run included the following additions:

• Added measures. The Port staff reviewed the list of available measures within the measure database and selected a set of commercial and industrial sector measures.

• Where appropriate, the added measures were modeled as early retirement. Comparison to 2014-2023 10-Year EE Potential Studies The total KWH savings for the overlapping period 2018-2023 increased by 84% from the targets adopted in 2013. New program processes have made participation easier for customers. The Port is exploring opportunities for expanded measure offerings and programs in order to achieve the increased savings goals. The Port has had a limited number of customers taking advantage of the Port’s EE program for a variety of factors:

• Port Electric Customers are also Port tenants. - The Port has approximately 135 electric customers. The Port’s customer profile is 100% Commercial/Industrial. Of these 135 customers, only a small percentage of customers have energy savings potential. For example, a large majority of customers at the Airport rent hangar space to store planes.

• Reluctance to upgrade due to limited duration of lease - Tenants are hesitant to invest in EE upgrades due to the length of their remaining lease. The Port’s tenants typically implement EE measures when they renew their lease and improve their building and/or space assignments.

• Port’s tenants sublease space to their customers including passing utility cost. In the case where a Port tenant subleases space to a third-party and the third party is responsible for utilities, the Port tenant is reluctant to invest in EE measures as they do not receive the benefits of those investments.

1. Base Case Run. This modeling run includes no changes or adjustments to Rancho Cucamonga’s current portfolio of energy efficiency programs.

2. Final Run. Rancho Cucamonga’s Final Run included the following adjustments to their Base Case Run:

• Expanded measure list. Navigant modeled a number of measures—not currently offered in

Rancho Cucamonga’s portfolio—to provide a picture of potential savings should Rancho decide to expand their current programs. The team used various sources and studies throughout California and the nation to inform this expanded measure list.

• Not claiming Codes and Standards savings. Rancho Cucamonga will not be claiming savings from codes and standards for this study.



Comparison to 2014-2023 10-Year EE Potential Studies The model used to create the current 10 year EE goals is similar to the one previously used in 2013 but with a few key differences. One of the most significant changes to the model is the improved calibration. The model now incorporates historical program savings using actual savings as identified in E3. With the prior model calibration, targets were set above actual historic achievement leaving a large percentage of previously established goals not met. This new calibration has made the current 10-year EE goals more accurate and attainable. Other programs and measures were evaluated but many are still not applicable for the current customer base. Customer participation in existing programs has continued to be a challenge since the majority of the commercial businesses were new developments that met or exceeded Title 24 standards and are now just hitting their 10 year mark. As energy efficiency measures and technology continues to advance, there will be more opportunities to explore new programs and continue to increase energy savings.

1. Base Case Run. This modeling run includes no changes or adjustments to Redding’s current portfolio of energy efficiency programs.

2. Final Run. Redding added streetlights to its program offerings starting in 2016 for the Final Run.



Comparison to 2014-2023 10-Year EE Potential Studies The years 2018-2023 overlap between the two 10-year study periods. Redding’s current 10-year goals are about 110% of the goals established in the prior study. There are two reasons for these higher goals:

• Redding added LED street lighting upgrades to their programs. • The forecast of retail sales in 2017 is approximately 10% lower than the retail sales forecast in 2012.

RIVERSIDE PUBLIC UTILITIES Riverside Public Utilities (RPU) 10-Year EE Potential Studies – At a Glance

• The Navigant 10-Year EE Potential Study resulted in an average annual target of 0.76% of forecasted retail sales. RPU intends to adopt a 10-year (2018-2027) Average Annual Target of 1.0% of forecasted retail sales subject to final approval by the governing body expected in April or May, 2017.

• The annual targets are reported as GROSS savings. • Riverside Public Utilities EE Potential Study does NOT include savings from future updates to Title

24 Building Energy Efficiency Standards in establishing the annual targets • The baseline for Energy Efficiency measures is EXISTING CONDITIONS.


1. Base Case Run. This modeling run includes no changes or adjustments to Riverside’s current portfolio of energy efficiency programs.

2. Final Run. Riverside’s Final Run included the following adjustments to their Base Case Run:

• Expanded measure list. Included streetlighting phase in starting in 2018. • Utilized a three-year average calibration target rather than 2015 alone.

Comparison to 2014-2023 10-Year EE Potential Studies The 2018-2017, 10-year EE potential study performed by Navigant resulted in an almost identical target when compared to the 2014-2023. Market potential was only 0.02% higher when the study was performed during the last cycle versus the current potential study cycle. Current market conditions throughout RPU’s service territory are very similar to the last cycle with the majority of the potential within the commercial customer segments. This is also where RPU intends to focus most of its program resources. Additional efforts are planned to target, hotels/motels and grocery store commercial customers. On the residential side there is potential in the behavioral program category. RPU will be launching a pilot customer engagement/behavioral residential program in FY 2017/18. If the program is well received by customers it may be expanded in future years.

2. Final Run. Roseville’s Final Run included the following adjustments to their Base Case Run:

• Added Streetlighting Program. • Added Commercial Sector Behavioral Program. • Increased promotional costs by 10%. • Increased incentives by 10%. • Claim gross rather than net savings



Comparison to 2014-2023 10-Year EE Potential Studies Roseville Electric Utility’s program performance against the targets for the prior three fiscal years average .86% of energy sales; however, when averaged over ten years, the results are .68%. These results are primarily due to the rapid adoption of interior and exterior LED technology and the implementation of the Home Energy Reports residential behavior program in recent years. Roseville is forecasting the market will be saturated with LED in 2018. California Title 24 building codes influence what energy efficiency retrofit savings are eligible to apply towards AB2021 targets. Title 24 set the direction to achieve net zero energy in new homes after 2020. At this time it is unclear how Title 24 will be revised to achieve the net zero home or what impact this will have on reportable energy efficiency savings for retrofit residential home programs. Recognizing the uncertainty with legislation and building codes, Roseville Electric Utility is proposing an average target for energy reduction of .76% over 10 years. These targets are realistic, achievable, cost effective and reliable as required by AB 2021 and can be funded with the 2.85% public benefits charge directed by AB 1890.

Comparison to 2014-2023 10-Year EE Potential Studies Several traditional sources for energy efficiency potential are waning due to an increasingly efficient baseline from high measure saturation and more stringent energy efficiency codes and standards. Measures categories with reduced savings compared to the 2013 study include residential cooling and shell, electronics, and non-residential refrigeration, resulting in reduced annual incremental market potential compared to the 2013 study of 74 GWh (-149%) for 2018 and 77 GWh (-52%) for 2023. Furthermore, SMUD’s residential new construction program is no longer considered an energy efficiency program due to poor cost-effectiveness resulting from reduced savings from an improved Title 24 baseline, eliminating 13 GWh (-9%) of incremental market potential for 2023. Sources of increased market potential include residential lighting, pool pumps and refrigerators, home performance retrofits, and non-residential process measures, contributing an additional 34 GWh in 2018 (+22%) growing to 53 GWh in 2023 (+36%). Comprehensive non-residential measures will add another 20 GWh in 2023 (+13%). Codes and standards savings were not included in SMUD’s 10-year goals resulting from the 2013 potential study, and will now add 37 GWh (+24%) to 2018 incremental market potential and 54 GWh (+36%) in 2023. The net impact of the above changes on annual incremental market potential is neutral for 2018 and a 26% increase for 2023.

1. Base Case Run. This modeling run includes no changes or adjustments to Silicon Valley Power’s current portfolio of energy efficiency programs.

2. Final Run. Silicon Valley Power’s Final Run included the following adjustments to their Base Case Run:

• Expanded measure list. Navigant modeled a number of measures—not currently offered in

Silicon Valley Power’s portfolio—to provide a picture of potential savings should Silicon Valley Power decide to expand their current programs. After review, Silicon Valley Power added the following commercial sector measures to their program portfolio: - Retro-commissioning - Pump and Fan Variable Frequency Drive Controls - Whole Building Retrofit - Comprehensive Rooftop Unit Quality Maintenance (AC Tune-up)

• Increased incentives by 10%.



Comparison to 2014-2023 10-Year EE Potential Studies The years 2018-2023 overlap between the two 10-year study periods. Silicon Valley Power’s current 10-year goals are about 87% of the goals established in the prior study even though it did add new measures to its portfolio.

TRUCKEE DONNER PUBLIC UTILITY DISTRICT (TDPUD) Truckee Donner Public Utility District 10-Year EE Potential Studies – At a Glance

• 2018-2027 Average Annual Target: 0.45% of forecasted retail sales. • The annual targets are reported as GROSS savings . • Energy savings from future updates to Title 24 Building Energy Efficiency Standards are NOT

included in the annual targets. • The baseline for measures is CODE, except for select measures.


1. Base Case Run. This modeling run includes no changes or adjustments to Truckee Donner’s current portfolio of energy efficiency programs.

2. Final Run. Truckee Donner’s Final Run included the following adjustments to their Base Case Run:

• Expanded measure list. Navigant modeled a number of measures—not currently offered in Truckee Donner’s portfolio—to provide a picture of potential savings should Truckee Donner decide to expand their current programs. The modeling team used various sources and studies throughout California and the nation to inform this expanded measure list.

• Increased promotional costs by 50%. • Claim gross rather than net savings.



Comparison to 2014-2023 10-Year EE Potential Studies These targets are based on the TDPUD’s solid documented energy saving results for the past but also acknowledges that, over a 10-year period, maintaining the District's energy savings AND cost-effectiveness will become increasingly difficult as the District moves past the 'low hanging fruit' and we start to saturate some programs. This trend of declining energy savings and increasing program costs over times has been well documented in California's electric utilities. The District has a unique load-profile (weekend, holiday, and winter peaking), customer base (predominately residential with the remainder being small business/commercial), and large number of 2nd homes and transient population. Changes in the regulatory environment, primarily the application of new Codes and Standards (C&S) to retrofits, will diminish the significant impacts of the TDPUD’s residential CFL & LED programs. The model currently used to develop the 10-year EE potential goals is similar to the one used to develop the 2014-2023 potential goals, with the following key differences:

• Updated Measure Impact/Cost Information – the modeling team has significantly improved the measure level inputs using the Technical Reference Manual (TRM) recently developed by the POUs, as well as the most recent CPUC database of available measures with impacts and costs at the climate zone level.

• Measure Impacts Include C&S Effects – the new ELRAM includes the most recent (C&S) impacts to measure savings, but does not include future or planned C&S impacts not currently adopted. This is a key factor in the decrease of the TDPUD’s overall EE potential.

The years 2018-2023 overlap between the two 10-year study periods. Truckee Donner’s current 10-year goals are about 71% of the goals established in the prior study. For the current 10-year goals, Truckee Donner claims gross rather than the net savings targets claimed in 2012. There are several reasons for these lower goals:

• The forecast of sales in 2016 is about 10% lower than the forecast of sales in 2012. • The 2016 calibration target is about one-third the amount of the 2012 calibration target. The

current calibration reflects the average savings of 2013, 2014, and 2015. • The application of C&S to residential lighting retrofits has greatly understated the actual EE

Savings and makes Residential Lighting Programs, on paper, not cost effective. This is a larger portion of TDPUD’s past savings, including 37% of savings in 2016.





• TDPUD has achieved significant EE savings over the last 10 years and are seeing saturation in some previously cost-effective programs.

TDPUD’s targets are reasonable and reflect our best forecast, however in some cases there are EE model limitations that do not accurately model TDPUD’s unique load profile and customer base. For example, the 4th highest potential EE savings program for 2027 on this model are shade trees for TDPUD’s cool, forested environment and non-air conditioned customer base.

TURLOCK IRRIGATION DISTRICT Turlock Irrigation District 10-Year EE Potential Studies – At a Glance

• Calendar Year 2017-2026 Average Annual Target: 0.60% of forecasted retail sales • The annual targets are reported as NET savings. • Energy savings from future updates to Title 24 Building Energy Efficiency Standards ARE included

in the annual targets. • The baseline for measures is the applicable CODE.


1. Base Case Run. This modeling run includes no changes or adjustments to Turlock’s current portfolio of energy efficiency programs.

2. Final Run. This modeling run uses Turlock’s chosen adjustments (listed below) to various features within the model to increase energy savings goals:

• Calibration factor changed from 100% to 150%, increasing forecasted achievable

savings. • Included estimates of savings from new programs that are currently not in our portfolio of

programs.



Comparison to 2013-2022 10-Year EE Potential Studies The 2017-2026 Targets (2017 Targets) are equal to 2013-2022 Targets (2013 Targets) on a % of forecasted retail load basis (i.e. they are both about 0.6% of forecasted retail sales). However, they differ on a year-by-year comparison. The 2017 Targets include savings from codes and standards that were not included in the 2013 Targets. Hence, the 2017 Targets show more achievable savings in the early years. In addition to supporting studies to develop future codes and standards, we have several planned activities to achieve more energy efficiency savings. For example, this year TID began working with local school districts to assist with Prop 39 projects and provide rebates for energy efficiency projects.

CITY OF UKIAH City of Ukiah 10-Year EE Potential Studies – At a Glance


included in the annual targets. • The baseline for measures is CODE for deemed measures, except for the non-residential lighting

and custom programs, which use EXISTING CONDITIONS as the baseline. Navigant used their Electric Resource Assessment Model (ELRAM) to estimate achievable energy and demand savings over a 10-year forecast period. The modeling team forecasted these savings using two modeling steps:

1. Base Case Run. This modeling run includes no changes or adjustments to Ukiah’s current portfolio of energy efficiency programs.

2. Final Run. Ukiah chose to call their Base Case Run as Final and made no adjustments to modeling scenarios.

Comparison to 2014-2023 10-Year EE Potential Studies For several years, the City’s energy efficiency programs had been operating with a balance forward on a year to year basis. In FY16, that was not the case. In FY16, the balance being carried forward in the PB funds had been expended. Moving forward, rebate amounts and rebate caps were also restructured in attempt to make available funding stretch to serve more customers and more projects. The result is that customer co-pay requirements increased which reduced participation in Ukiah’s EE programs.

The model used to develop these goals is an updated version of the one utilized by the Navigant team in 2012 for CMUA and is similar in design, utilizing much of the same measure data information, as the California Public Utilities Commission’s (CPUC) Potential Goals (PG) Model used for California’s Investor Owned Utilities (IOUs). Assembly Bill 2021 directed the California Energy Commission (CEC) to identify all potentially achievable cost-effective electricity and natural gas efficiency savings and establish 10-year statewide energy efficiency savings targets. Originally intended to occur every three years, Assembly Bill 2227 changed the frequency of the energy efficiency 10-year target setting requirements to once every four years. CMUA engaged the Navigant team to assist the 38 CMUA members meet the CEC requirement to receive from CMUA members their 10 year DSM program targets.

2. Key Issues and Updates Since the 2012 Potential Study

This study provides an update to the 2012 Potential Study. The 2012 Potential Study developed estimates of technical, economic, and market potential for participating CMUA members. For both the current and 2012 Potential Study, Navigant utilized its Electricality Resource Assessment Model (ELRAM) as well as the related Natural Gas Resource Assessment Model (NGRAM) for the City of Palo Alto. The 2012 model was the basis for the current CPUC Potential Goals (PG) model with both ELRAM and the CPUC PG models evolving over the years since 2012. The new ELRAM is more powerful in its computational capabilities and agile in its scenario development capabilities. It also now includes a robust and easy to use output viewer, which allows the client to view potential savings estimates in a variety of ways without loading the entire ELRAM. Other improvements include:

• Improved savings target calibration – the model calibrates using actual savings per end-use category by program as identified in the SB 1037 reports.

• The capability to adjust potential either to meet specific budget limitations or to meet specific target goals by program.

• Increased decision type flexibility and existing baseline capabilities – the model structure now allows for dual baseline measures and “to code” measures that exist from an existing baseline of a measure rather than a code baseline.

• Expanded building types – ELRAM provides model results at the building type level for both the residential and commercial segments. The 2012 model only provided a rolled up commercial result.

• Expanded industrial and agricultural assessments - ELRAM provides model results for up to 15 industrial and 9 agricultural NAICS categories. The 2012 model only provided a roll up industrial results and no agricultural measures.

• Improved documentation – ELRAM is extensively documented in a Word document and within the model. Each sheet of the model contains a concise explanation of each formula and the purpose of each sheet.

2.1 Relationship of ELRAM to the Current CPUC Model

Since 2011, Navigant has been conducting the CPUC’s PG study; Navigant is currently on contract to continue supporting the study through 2018. The CPUC model creates forecasts of the technical, economic, and market potential across four utilities, 16 climate zones, and six sectors. The study is publically vetted through a stakeholder process and is used by the CPUC to set Investor Owned Utilities (IOU) goals, used by the CEC to inform Integrated Energy Policy Report (IEPR) demand forecast, and relied upon by the California Independent System Operator Corporation (CAISO) for planning purposes


Page 4

The PG Model currently used by the CPUC to establish potential goals for the California IOUs is similar to the CMUA ELRAM. The PG model primarily differs in two ways:

• The PG model platform is Analytica and ELRAM is Excel

• The PG model market adoption algorithm is similar to the ELRAM approach in that they both use payback based Bass diffusion curves. However, the PG curves are based on lifecycle full equipment costs and paybacks while ELRAM is based on first cost measure payback. Results are similar but with ELRAM more responsive to changes in incentive levels when performing scenarios based on adjusting incentive levels.

Analytica was chosen as the platform for the PG model because it can handle larger datasets within one model run (it runs all the IOUs at one time). Navigant has found that client preference to platform varies and therefore provides both an Analytica and Excel Potentials Model. For CMUA, Excel is considered the better platform as each model application (the 38 POUs) will each require unique adjustments and considerations. Excel is more amenable to making multiple modifications quickly. The basis for the change in the adoption algorithm between ELRAM and the PG model was the decision to include a financing option within the PG model. Simple payback doesn’t work well with financing. Table 2-1 provides a comparison of model attributes between ELRAM and the PG model.

2.2 Ability to Claim Codes and Standards (C&S) Savings

Codes and standards affect energy efficiency programs in two different ways. Codes and standards increase overall energy savings because they require customers to install high-efficiency measures in lieu of baseline equipment. The mandates can cause markets (a) to achieve higher levels of adoption and (b) to achieve those levels faster than possible in the absence of the legal mandate.


Page 6

However, codes and standards also reduce the savings potential from traditional utility programs. C&S updates increase the baseline efficiency of utility program measures, thus reducing the savings that POUs can claim as a result of the program. The effects of state and federal standards on voluntary programs are quantified by the percentage impact to unit energy savings of affected voluntary program measures. The energy savings impact is quantified as the ratio of the measure unit energy savings (UES) under the new standard to the measure UES using the baseline efficiency, as shown in the following equation:

𝐼𝐼𝐼𝐼𝐼𝐼𝐼𝐼𝐼𝐼𝐼𝐼 𝑃𝑃𝑃𝑃𝑃𝑃𝐼𝐼𝑃𝑃𝑛𝑛𝐼𝐼𝐼𝐼𝑛𝑛𝑃𝑃𝑌𝑌𝑌𝑌𝑌𝑌𝑟𝑟 =𝑈𝑈𝑈𝑈𝑈𝑈 𝑢𝑢𝑛𝑛𝑢𝑢𝑃𝑃𝑃𝑃 𝑛𝑛𝑃𝑃𝑛𝑛 𝑠𝑠𝐼𝐼𝐼𝐼𝑛𝑛𝑢𝑢𝐼𝐼𝑃𝑃𝑢𝑢𝑈𝑈𝑈𝑈𝑈𝑈 𝑢𝑢𝑛𝑛𝑢𝑢𝑃𝑃𝑃𝑃 𝐼𝐼ℎ𝑃𝑃 𝑏𝑏𝐼𝐼𝑠𝑠𝑃𝑃𝑏𝑏𝑏𝑏𝑛𝑛𝑃𝑃

Impact percentages vary by year because standards take effect in different years. Therefore, “vectors” of impact percentages were developed for utility program measure affected by C&S to capture the impact in each future year. For utility program measures not affected by any new C&S, values of the impact percentages are 100%. The energy savings potential of the CPUC PG model C&S advocacy program is determined based on the C&S energy savings defined in the CPUC 2006-2008 C&S program evaluation report1. ELRAM included within its modeling structure the ability of POUs to also claim C&S energy savings if they participate in some way with C&S advocacy. The method involves taking the C&S claims by sector for the closest IOU and pro-rating those savings based on sector sales.

2.3 Emerging Technologies

The Navigant team depended on the analysis of emerging technologies (ETs) as defined in the 2015 CPUC PG modeling effort. ETs are defined as meeting one or more of the following criteria:

• Not commercially available in today’s market but expected to be available in the next 3-5 years

• Commercially available but representing less than 5% of the existing market share • Costs and/or performance are expected to improve in the future

The measures identified as ET in the CPUC PG model and included in ELRAM are:

• Residential, commercial, industrial, and street lighting LEDs • MEF 2.87 Clothes Washers • EF 1.19 Dish Washers • Heat Pump Clothes Dryers

2.4 Electric Vehicles (EV) and Solar Photovoltaic (PV)

The Navigant team’s approach to modeling EV/PV adoption rates, and corresponding potential, was established in recognition of the following study considerations:

1.) There does not currently exist a unified and/or approved approach for estimating EV/PV potential across utilities within CMUA.

2.) The subsequent methodology must, to the extent possible, leverage data available to all utilities to facilitate both consistency and transparency in modeled results. Subsequently, individual utilities should have the opportunity to refine the models with utility-specific information and growth projections.

In support of these objectives, the Navigant team leveraged utility-specific information from the California Energy Commission (CEC) Integrated Resource Planning (IRP) process; specifically, we developed regression models to forecast EV/PV adoption rates and potential using data from the 2016 Integrated Energy Policy Report (IEPR).2 Regression modeling is a form of analysis that attempts to quantify the behavior of an uncertain parameter relative to other observable, and potentially influential, variables. The most commonly used approach to capture this relationship is the linear regression3 model. For a set of predictive variables:

],,...,,[ 21 nXXX4

and constants,

],,...,,[ 10 nβββ The linear regression model is expressed by,

nn XXY βββ +++= ...110 In this study, the parameter “Y” represents a modeled adoption rate and/or sector-level consumption target per year by EV/PV, while the predictive variables “Xi” represent the influencing parameters (i.e., years).

2 https://efiling.energy.ca.gov/Lists/DocketLog.aspx?docketnumber=15-IEPR-03 (Mid Demand Case) 3 Nonlinear regression is another form of regression analysis in which the relationship between the dependent and independent variables are characterized by a nonlinear combination of model parameters. However, there is generally no closed-form expression for the best-fitting parameters, as there is in linear regression, and the data are fitted by a heuristic of successive approximations. 4 In this case, the predictive variable would be previous years for which the IEPR forms provided former Electricity Consumption by Sector (GWh), Peak Demand (MW), etc.

The most common method of estimation, being the focus of this discussion, is the ordinary least squares approach. This method calculates values for the regression constants by minimizing the sum of squared residuals - a residual being the difference between a regression output and known value:

∑ −= i

In this equation, iY and ∧

iY represent the regression output and known data points, respectively. Minimization of this function results in a set of simultaneous linear equations which can be solved for the estimator constants. Figure 2-1 provides an illustrative example of the components involved in a least squares analysis. The linear curve represents a regression model output, while the discrete data points (i.e., blue diamonds) correlate to known data. The vertical bars in red represent the calculated residuals, the squared minimization of which will provide the best fit regression model.

Source: Navigant: It is hardly obvious why one would choose the best fit model by using the least squared approach. Minimizing the sum of errors in absolute value6 seems more readily intuitive.

5 For the sake of visual practicality, Exhibit 1 represents a regression model with two unknown constants – or more precisely: XY 10 ββ +=

. This equation generates a linear curve, whereas a model with “n” constants would be

characterized by a “hyperplane” in n-space which would be much more difficult illustrate. 6 The absolute value prevents large negative and positive errors from canceling out; yielding a model with minimum error that fits the data poorly.


Page 9

However, there are many qualities that make the least squared approach both computationally and statistically attractive. For one, it is very easy to calculate from a software perspective. Expressing the sum of squared errors mathematically, and employing calculus theory to derive the set of constants to minimize this sum, yields “n” equations and “n” unknowns to solve. The approach also possesses significant statistical properties that may be used to gauge the accuracy of regression findings. The calculation of the R2 value,7 or coefficient of determination, represents the proportion of variability in a data set that is accounted for by a statistical model and is defined to be:

where _Y represents the mean of the observed data. Overall, a larger R2 value indicates a more

accurate regression model. When modeling EV/PV adoption / potential, the Navigant team developed linear, polynomial, exponential, etc. regression models for each utility using data from the 2016 IEPR. To maximize the accuracy of modeled findings, the model with the highest R2 value was used to forecast the first estimate of EV/PV adoption rates and potential for each utility. Figure 2-2 provides an example of the Navigant Team’s modeling output for EV Sales (GWH) within the residential sector. Once the first set of forecasted estimates were provided to each utility, we collaborated with utility representatives to identify whether the source data could be improved through more recent or more utility-specific information. In these cases, the models were updated with improved / more accurate data and a new set of forecasting outputs were provided to each utility. It should be noted that the value of a regression model is directly dependent on the quality of data included. Accordingly, the Navigant team strives for transparency when detailing the sources of information included through each analysis, and to remain cognizant of outliers which may bias results. This transparency also ensures that individual utilities are aware of where updated / utility-specific data would provide the most value to the regression model.

2.4.1 Photovoltaic System Dampening Effect

A Solar PV dampening methodology is added to the model based on the forecast of PV generation in a POU service territory expressed as a percent of utility sales. The dampening adjustment is applied to the consumer’s willingness to install measures by reducing the willingness as the share of PV generation to utility sales increases. Unfortunately, the Navigant team found no supporting research for calibrating this dampening factor. The dampening effect may in fact be minimal giving that those who install PV are generally more inclined to make their homes energy efficient and thus install a deeper level of efficiency measures. Additionally, the installation of PV may act as a prod to learn more about energy efficiency, therefore potentially increasing installation of energy efficiency measures. Given the lack of evidence one way or another, this dampening effect has been set to 0.0% with no dampening occurring.

3. Modeling Methodology

The Electricity Resource Assessment Model (ELRAM) is an electricity energy efficiency potential model designed to estimate technical, economic, and program (market) energy efficiency potential for a utility’s service area. Developed by Navigant, the model forecasts energy savings and demand reduction potential within the residential, commercial, and industrial sectors over a forecast period of typically 20 years. Since its initial development in 2007, the model has been used by over 50 different electric utilities across the country to identify future energy efficiency potential.

3.1 Key Design Elements ELRAM is a stock/flow Excel spreadsheet model based on the integration of energy efficiency measure impacts and costs, utility customer characteristics, utility load forecasts, and utility avoided costs and rate schedules. ELRAM utilizes Excel as the modeling platform due to the transparency in the DSM potential estimation process, and because of the ubiquitous knowledge of the platform in general. Excel also allows the team to customize ELRAM to accommodate the client’s unique set of input characteristics and utility data. The model utilizes a “bottom-up” approach, beginning with study area building stocks, equipment saturation estimates, forecasts of building stock decay and new construction, energy efficiency technology data, past energy efficiency program accomplishments, and decision maker variables that influence the program scenarios. A key component of ELRAM is the decision maker function used to estimate annual participation in utility programs. ELRAM develops “Measure Payback Response Curves” that are calibrated to historical utility program achievements. These measure level curves are founded on the Bass Diffusion Model developed by Dr. Frank Bass. The Bass Diffusion Model describes the process of the adoption of products as an interaction between users and potential users. The decision maker function estimates a measure by measure elasticity response to first cost measure payback. The elasticity coefficient is calculated for these measures in the base calibration year using measure-level utility program achievements and first cost measure payback. Utilizing this elasticity based decision process allows for easy to create scenario options based on changing the size of measure level incentives. In addition, other input variable flexibilities are included within ELRAM to allow for many different scenario considerations.

3.2 Potential Estimates The model develops estimates of technical, economic, and market potential. Figure 3-1 illustrates these types of energy conservation potential, as defined below: Technical Potential. ELRAM calculates technical potential as the product of a measure savings per unit, the quantity of applicable units in each facility, and the number of facilities in a utility’s


Page 12

service area. This potential savings assessment includes measures that may not be cost-effective, and therefore provides an upper bound of efficiency potential regardless of cost or market penetration. All baseline units are considered available regardless of measure life. No net-to-gross adjustments occur with technical potential. Economic Potential. ELRAM estimates economic potential as the amount of technical potential that is cost-effective, as defined in this case by the results of the Total Resource Cost (TRC) test. The TRC test is a cost-benefit analysis of relevant energy efficiency measures, excluding market barriers such as lack of consumer knowledge. Benefits include the avoided costs of generation, transmission and distribution investments, avoided fuel costs, and other benefits that may accrue to participants and/or to the utility. Costs vary by economic test but may include incremental technology cost, incentives, administrative costs, and/or lost revenue. The economic screen is set to 1.0 to determine Economic Potential. There are no net-to-gross adjustments. Maximum Market Potential. ELRAM screens the amount of economic potential that utility programs could capture over the forecast period. The measure level economic screening value for maximum market potential can be set to less than 1.0, but results at the program level have a goal of having an overall economic screen of 1.0 or better. This allows the program to include a mix of measures above and below the 1.0 screening threshold. This adjustment factor can vary by program. In addition to the economic screening value, maximum market potential includes the effects of decision maker awareness of each measure and if aware, their willingness to install the measure. Market Potential. ELRAM uses a fourth step for calculating achievable energy savings at the market level using simple payback elasticity. The achievable market potential uses the remaining maximum market potential at the measure level available each year and applies a decision maker simple payback elasticity coefficient to identify yearly savings available in the marketplace. The model calculates this payback elasticity based on historical program achievements and the identified incentive levels by measure. This step provides realistic forecasts of market potential given incentive and program budget levels, which can change over the forecast period.

3.3 Approach to Estimating DSM Potential

ELRAM utilizes “Measure Payback Response Curves” to calculate market potential by year. The method for creating these curves comes from the methodology used for the Bass Diffusion Model developed by Dr. Frank Bass. The Bass Diffusion Model describes the process of the adoption of products as an interaction between users and potential users. The decision maker function estimates a measure’s elasticity response to first cost measure payback calculated in the base calibration year. This base year uses measure-level utility program achievements and first cost measure payback. First cost measure payback does not include any savings from extended measure life of changes in maintenance costs. Utilizing this elasticity based decision process allows the model to create scenario options based on changes to measure level incentives. In addition, ELRAM includes other input variable flexibilities to allow for many different scenario considerations including program budget levels and program promotion costs.

3.4 Model Structure and Flow ELRAM includes nearly 40 distinct worksheets including input, calculation, and output pages, as well as a Scenario Dashboard that offers modelers a quick way to interact with the model and produce different scenario runs. The variables available on the dashboard include:

• Economic test screens • Beyond first measure life considerations • Fiscal variables including:

o Incentive level o Administrative costs o Program budget limitations

There is also an “output viewer” connected to the results of the model which allows the client to view potential savings estimates in a variety of ways. Figure 3-2 provides a general overview of the data flow through the ELRAM model. The model structure can vary from client to client depending on available data and output needs.

Figure 3-2. ELRAM Data Flow Overview

Source: Navigant Successful potential savings forecasts rely on high quality and accurate data inputs into ELRAM. These inputs fall into four categories including:

• Utility Data. Navigant worked closely with the CMUA utilities to gather all utility specific data such as energy (kWh) and demand (kW) forecast estimates, avoided costs, past program savings achievements for use in calibrating ELRAM, customer rate classes, and discount rates. Navigant also relied on the Quarterly Fuels and Energy Reports submitted by the utilities to the California Energy Commission for commercial and industrial sales information by NAICS.

• Customer Data. Navigant relied on the CPUC PG model inputs by climate zone to provide customer characteristic data by measure. The CPUC data relied on statewide Residential and Commercial building saturation surveys.

• Measure Data. Navigant relied on the CPUC PG model dataset of energy efficiency measures as well as the POU Technical Reference Manual (TRM) to characterize the measures included in the study. These characteristics include costs, energy and

• Measure Availability. ELRAM uses building stock inputs along with the availability of technology density each year to estimate potential energy savings throughout the forecast period. Navigant relied on the CPUC PG model inputs by climate zone for this information.

The outputs from ELRAM accomplish multiple objectives, including:

• Determining the total technical, economic, and market potential of energy savings available over the forecast period, both annually and cumulatively; the model calculates these potential estimates at the sector, building type, program type, and end-use classification levels

• Providing guidance for identifying 10-year energy efficiency program goals at an aggregate level, as well as at the measure category level. ELRAM calibrates calculations to past utility achievement levels to ensure continuity with past utility efforts

• Identifying cost-effectiveness using multiple cost effectiveness tests

• Identifying specific costs and benefits, including administrative, incentive, and technology costs, along with avoided cost and reductions in other resource requirement benefits (such as water use reduction)

3.5 Calculating Energy Efficiency Potential

The results of ELRAM are designed to accomplish multiple objectives, including: • Determining the total cost-effective energy savings available over the forecast period,

both annually and cumulatively. The model provides estimates at the sector, program type, and end-use classification levels.

• Providing guidance for the utility’s energy efficiency goals at an aggregate level and at the measure category level, where appropriate. As discussed, the ELRAM calculations are calibrated to past utility achievement levels to ensure continuity with past program achievements.

The model partitions its assessment of each measure into technical, economic and achievable potential. Each assessment includes building stock estimates, technology densities, and measure impacts, with each using a different algorithm.

3.5.1 Measure Types Addressed

ELRAM recognizes the following measure types:

• Replacement on Burnout (ROB): Implementation of an energy efficient measure after the existing equipment fails.

• Retrofit (RET): Immediate installation of an energy efficient measure that improves the efficiency of an existing technology. The lifetime of the base technology is not a factor as


Page 16

retrofit measures generally do not replace existing technologies. The energy impact is therefore only the amount of improvement to the existing technology.

• Dual Baseline (DUB): The dual baseline measure type is an early replacement that replaces an existing technology before the end of useful life. However, savings is calculated using a less efficient “as found condition” baseline for the first part of the remaining useful life (RUL), and a “code condition” for the second portion of the RUL. These results in higher initial energy savings under the first baseline, and lower savings under the second baseline once the measure would have reached the end of its effective useful life (EUL). Measure costs are also adjusted to reflect the change in baselines. 9

• Behavioral Programs (BEH): Programs designed to influence consumer behavior through the provision of training and/or information. As with emerging technologies, achievable potential is calculated using a Bass diffusion model rather than the traditional measure payback.

• Low Income (Low): Measures that are implemented as part of a low-income program. • New Construction (NEW): Installation of a measure or package of measures at the

time of construction. • Demand Response (DR): Strategies specifically designed to reduce peak demand.

There is generally very little energy savings associated with these strategies.

3.5.2 Financial Tests Calculated

ELRAM calculates several financial tests and measurements, including:

• Total Resource Cost (TRC): This test includes all quantifiable costs and benefits of an energy efficiency measure that may accrue to participants or the utility. For example, a measure passing the TRC test is cost effective from this perspective if the sum of its avoided costs and other benefits accruing to participants or the utility are greater than the sum of the measure costs and the utility’s administrative costs.

• Program Administrator Cost Test (PAC): This test measures the costs of an energy efficiency program based on the costs incurred by the utility (including incentive costs) and excluding any net costs incurred by the participant. For example, a measure passing the PAC test is cost effective from this perspective if the sum of the avoided costs (costs avoided by the measure’s energy and demand savings) and other utility benefits are greater than the utility’s costs to promote the measure, including incentives provided to customers.

• Ratepayer Impact Measure Test (RIM): This test measures what happens to a dwelling or business’ electric bills or rates due to changes in utility revenue and operating costs caused by the program. For example, a measure passing the RIM test is cost effective from this perspective if its avoided costs are greater than the sum of the utility’s costs and the “lost revenues” caused by the measure.

• Participant Cost Test (PCT): This test measures the quantifiable benefits and costs to the customer due to participation in the program. For example, a measure passing the PCT test is cost effective from this perspective if the reduced electric costs to the

9 See the Dual Baseline section 3.5.6 for more detail.


Page 17

participating customer from the measure exceed the after-incentive cost of the measure to the customer.

• Simple Customer Payback: This measurement calculates the incremental technology cost divided by the incentive and the reduction in the electric bill. If multi-life benefits and costs are considered, it also includes the PV of future technology costs and future incentives and bill reductions.

• Levelized Measure Cost/kWh: This measure multiplies the energy efficiency measure costs by the Capital Recovery Factor, and divides by the first-year kWh savings.

ELRAM calculates measure, program, end-use, building type, and overall portfolio level costs and benefits, and when applicable at both the net and gross levels. Net values take into account free riders by using net-to-gross adjustment values. The costs and benefits calculated include:

• Administrative costs (always gross) • Avoided cost benefits (always net) • Other utility benefits (always net) • Other participant benefits (always net) • Incentive costs (always gross) • Incremental technology costs (gross or net) • Utility bill reductions (gross or net)

Within the “Financial Tests” worksheet, these streams of costs and benefits are converted to a net present value using the discount rate. With this data, four financial tests identified above are calculated.

Total Resource Cost (TRC)10,11,12: The TRC test measures the net resource benefits from the perspective of all ratepayers by combining the net benefits of the program to participants and non-participants. The benefits are meant to be the sum of the avoided costs of the supply-side resources avoided or deferred, and other benefits that accrue to participants or the utility. The TRC costs encompass the cost of the measures/equipment installed, and the costs incurred by the utility. The formulation:

TRC = Benefits / Costs where:

Benefits = net avoided costs + net other utility benefits + net other participant benefits

Costs = gross administrative costs + net incremental technology costs

Program Administrator Cost Test (PAC) : Sometimes referred to as the utility cost test, this test compares the utility's avoided cost benefits with energy efficiency program expenditures (incentives plus administrative costs).

3.5.3 Approach to Multi-Life Benefits

3.5.3.1 Multi-Life Benefits

The ELRAM model has the capability of recognizing that the impacts of DSM measures may extend beyond the initial estimate of measure life. Taking this possibility into account can affect benefit/cost ratios, such as the TRC, PCT, PAC, and RIM, by incorporating future expectations of avoided costs, as well as changes in measure costs and impacts, and cumulative energy and demand impact estimates. The estimation of multi-life benefits and determined by the variable:

• Measure Re-Engagement. This variable estimates the share of measure installations

that continue to provide efficiency benefits at least equal to the initial DSM measure installed. The complimentary share of installations not part of re-engagement is returned to the population totals of available stock for program participation.

There are no new incremental savings accruing from the re-engaging population. However, cumulative savings must be adjusted in two ways. Using as an example a re-engagement rate of 85%, the first adjustment is for the 15% not re-engaging. This 15% goes back to the baseline population and their savings removed from cumulative savings. The second adjustment is for the 85% assumed to be re-engagers. For this group, adjustment to cumulative potential is dependent upon whether the savings are different from what was achieved at the time of the original participation. If unchanged, no changes to cumulative potential. If savings are different, then the cumulative potential is adjusted by this delta difference. At the point in time of re-engagement, factors may exist that affect the estimate of continuing DSM measure saving and costs.

• A code or standard (C&S) may have come into effect since the initial point of participation. The effects of the C&S become an attribution issue. Since C&S are mandatory, savings affected by C&S are attributed to the C&S. The share of savings may be 100% or may be a share lower than 100%. If 100%, then no further savings or costs are attributed to the DSM program measure. If the attribution is less than 100%, then the attribution share still applicable to the utility is accounted.

• A measure’s estimated energy savings may increase or decrease in the future. For example, LED lighting is still improving in efficacy and, as it does, savings per measure increase. In contrast, appliance recycling programs, such as refrigerator recycling, are expected to have lower savings per unit over time as the population of refrigerators becomes a more recent (more efficient) vintage each passing year.

• A measure’s estimated cost may increase or decrease in the future. For example, LEDs and other, newer technologies are expected to decline in cost as these become more popular in the marketplace. The declining cost of CFLs over the past decade is an example of such an effect.

Any changes in energy savings at the point of re-engagement are calculated. These changes in energy savings are applied to the Cumulative Potential and do not affect the Achievable Incremental Potential.


Page 20

Avoided cost of energy, capacity, and any externality that is quantified are all calculated per measure unit. The impacts are separated into “first life” avoided costs and “beyond first life” avoided costs. The “first life” values are the present value of avoided costs using measure life, the utility discount rate, and the utility’s avoided cost stream. The “beyond first life” estimate of avoided cost is calculated only for the population of “re-engagers”. For this population, the present value of future avoided costs beyond the first life15 is calculated starting at this future point in time. This calculation uses any revised future estimate of measure impact, along with measure life, the utility discount rate, and the avoided cost stream appropriate for that time frame. In a similar manner, the future cost for incremental technology is calculated.

3.5.3.2 Codes and Standards Modified Baseline Effects on Cumulative Potential

The effects of codes and standards within the ELRAM model are viewed as an attribution issue between what is credited to codes and standards and what is credited to the DSM program. The “Code Based Impact Change” identifies the specific codes and standards expected to affect measure savings over the forecast period. The effects to measure savings are in the form of time vectors where a specific code and standard is associated with the measures it is expected to affect. The measure effect is in the form of a percent change in savings starting at the point when the code and standard goes into force. As an example, if a specific code and standard effectively reduces saving by 50% starting in the year 2015, the DSM program’s first year incremental measure impact would be 100% of the estimated program impact up to the year 2015. Starting in 2015 and thereafter, the utility’s share of the measure savings is reduced by 50%, with the other 50% being attributed to the code and standard.

Treating the savings achieved by the DSM program after a code and standard goes into force is done in two parts. First addressed, at the moment the code and standard going into force, is whether there are any adjustments to the first measure lifetime savings, costs, and benefits. The ELRAM model treats these already exiting program achievements, benefits, and costs as unchanged (maintained) over the remaining first lifetime of the measure.

However, at the time of re-engagement, adjustments do occur. For those measures assumed to re-engage after the first lifetime is complete, the measure impacts, benefits, and costs are calculated based on the code and standard adjusted savings level. It is assumed that attribution of the savings transfers to the code and standard at this point forward. To accommodate this, the Cumulative Potential is adjusted downward to reflect the lowered savings resulting from the impact of the code and standard at the time of re-engagement. Additionally, post first lifetime benefits and costs are calculated to reflect the lower savings.

15 Several lifetimes may be calculated, depending on the measures estimated life and the length of the forecast period.


Page 21

3.5.4 Mutually Exclusive Measures

Two or more measures that each can replace the same base technology are considered to be mutually exclusive. Examples of mutually-exclusive measures are LED and CFL lamps of the same efficacy being in competition to replace an incandescent lamp. Mutually-exclusive measures are placed into competition groups with separate competition group identifiers for each group. Within the competition groups, the mutually-exclusive measures share the same base population, but each measure uses its own unique decision-maker adoption rate algorithm to estimate year-by-year achievable potential. The base population is reduced each year by the sum of the mutually-exclusive measures participation.

3.5.5 Interactive Effects

The energy and demand impacts form DSM measures can be affected by other measures or actions taken. ELRAM recognizes two forms of interactive effects. The first are interactive effects among measures within the same fuel type and end use. An example of a set of DSM measures that would be considered having interactive effects would be ceiling insulation, wall insulation, a high efficiency furnace, and energy efficient windows. Alone, each of these measures would have a specific energy savings impact. As a group or part of a group, the individual measures have lower savings. Within ELRAM, a unique interactive effects code is assigned to the set of measures considered to be interactive in this manner. The stand-alone measure impacts are identified as well as the savings if the entire set of interactive measures were implemented. The measure savings used in ELRAM is the pro-rated share of the individual measure savings to the group total. For example, if an interactive measure group included two measures, one with a stand-alone savings of 100 kWh and the other 200 kWh with a group implementation total of 250 kWh, the first measure’s model savings is 100/300*250 or 83.3 kWh and the second measure model savings is 200/300*250 or 166.7 kWh. The second type of interactive effect is among measures from different end-uses that impact the savings of the other. An example would be lighting measures. More efficient lighting produces less waste heat. This results in lower cooling but higher heating loads. The lighting measure energy savings would be increased by how much it reduces electric cooling and increased by how much it increases electric heating. The saturation of electric cooling and heating is taken into account. Effects on other fuels or commodities, such as increased natural gas heating loads or reduced water use, are accounted within the cost effectiveness calculations through increases or decreases in the billing for that fuel or commodity.


Page 22

3.5.6 Dual Baseline Measures

Certain DSM measures are candidates for an early replacement program that utilizes a dual baseline. A dual baseline approach calculates energy savings using a more complex method than is used by the majority of North American DSM administrators. Most jurisdictions use the effective useful life (EUL), or assumed average life of the new measure to calculate the annual savings of the new measure. An example is the replacement of an air conditioning system with one that uses energy more efficiently. For the EUL of the new system (for example, 25 years), the difference in energy use between the new system and the replaced one is claimed as the energy savings. A dual baseline approach uses, in addition to EUL, the remaining useful life (RUL) of the replaced equipment, which is the length of time the equipment is expected to remain in operation (the length of time until its EUL is at an end). Using a dual baseline approach in the example of the air conditioning system, the difference in energy use between the replaced and new system is claimed as savings only for the RUL of the replaced system. After the RUL (for example 10 years) of the replaced equipment and until the end of the EUL of the new equipment (15 years, if the new system is assumed to have an EUL of 25 years), the difference in energy use between the new system and the standard of equipment at that time is claimed as energy savings. This method takes into account improvements in technology and the market over time; even without an incentive, energy savings for some equipment will occur when old equipment is replaced, because the standard version of newer equipment uses less energy. In the year an energy-efficient measure is installed, if the replaced measure is still in working order, its RUL must be calculated based on its EUL and the length of time it has been in use prior to replacement. Figure 3-3 illustrates the two-step process.


Page 23

Figure 3-3. Two-part Calculation of Energy Savings Using a Dual Baseline Approach

Once calculated, energy savings are affected in the following ways:

• When a measure is replaced and it has a RUL, the full unitary savings value (the replaced measure’s estimated annual kWh usage minus the new measure’s estimated annual kWh usage) is calculated. These savings can be claimed for each year of the RUL of the measure (Figure 3-3, step 1).

• When the RUL of the replaced measure expires in the future, a new baseline for annual kWh savings must be used. This baseline is calculated using the most common energy use values for replacement products: either those legislated through codes and standards or those installed by common practice (Figure 3-3, step 2).

• If the replaced measure has reached the end of its EUL at the time of replacement, then the current code or most commonly used measure is used to calculate the energy savings, rather than the difference between the new measure and the replaced one.

3.5.7 Appliance Recycling

Appliance recycling measures need special treatment because of the unique characteristics of the base population. Unlike other base technologies, the used appliance stock available for recycling is constantly being refreshed with new populations of appliances. Due to past

improvements to appliance efficiencies (primarily codes and standards), the constantly refreshing population of available appliances for recycling is more efficient (and thus saves less energy) from year to year. Available populations of appliances for recycling may not change significantly from year to year, but the time vector of savings per unit does decline. The cumulative savings are accounted only within the timeframe of the estimated remaining life of the recycled appliance. The re-engagement calculations do not take place for appliance recycling measures.

3.5.8 Behavior Based Energy Savings Potential

Savings potential from behavior-based initiatives can be included in the ELRAM model by initiative and by building sector. Within ELRAM, behavior-based initiatives are defined as those providing information about energy use and efficiency actions, rather than financial incentives, equipment, or services. These initiatives use a variety of implementation strategies including mass media marketing, community-based social marketing, competitions, training, and feedback.16 Outcomes from behavior-based initiatives that result in energy savings can be broadly characterized as equipment-based and usage-based:

• Equipment-based behavior – Savings from the purchase and installation of higher efficiency equipment, relative to baseline conditions.17 Examples of equipment-based behavior include the replacement of lights with higher efficiency lights, purchasing Energy Star®-qualified appliances, and purchasing premium efficiency motors. In the ELRAM Model, these savings are modeled at the equipment level as contributions to the percentages of the population that are aware of the measure and that are willing to adopt this measure. Equipment-based behavior can be sub-categorized as:

o Non-incented equipment-based behavior – The purchase of higher efficiency equipment for which no incentives are provided.

o Incented equipment-based behavior– The purchase of higher efficiency equipment for which incentives are provided.

• Usage-based behavior – Savings from changes in usage and maintenance of existing equipment. Examples of usage-based behavior include turning off lights, unplugging electronics and chargers, programming thermostats, and improving the efficiency of equipment through modified maintenance practices. In the ELRAM model, these savings are modeled as an equipment-independent module with savings unassociated with equipment improvement.

The behavior measure savings used within ELRAM reflect estimates of usage-based and non-incented based behavior. The incented equipment-based behavior is assumed to be addressed by the utility’s other incentive-based DSM programs. Currently, the measure life is assumed to be one year for the residential sector based on enhanced billing programs, reflecting the need to continually reinforce the behavior program’s message to conserve and use energy efficiently. The commercial and industrial sector programs are assumed to have a measure life of five years based on the extensive training received by building operators. For the commercial sector, the program is based on a Building Operator Certification Program. For the industrial sector, the program is based on a Strategic Energy Management Program.

3.6 Creating Scenarios Based on Modifying the Incentive Level A fundamental element of ELRAM is the decision-maker algorithm. The function of measure calibration is to establish for each measure a baseline “Market Factor”, which is estimated based on first-cost measure payback and the achieved savings in the base year. This value is an elasticity coefficient used in the forecast period to estimate measure adoption. These incentive levels by measure are generally the actual incentives provided by the utility or they default to an input value, such as 50% of incremental cost. Once the baseline Market Factor is established, the incentive during the forecast period can be modified up or down. Changing the incentive changes the first cost measure payback with corresponding changes in measure adoption rates. These changes in adoption rates are established using the baseline Market Factor, which is unchanged, and the modified first cost measure payback. The scenario incentive level is expressed as a multiplier to the base scenario incentive. If the base incentives are expressed solely as a percent of incremental technology cost (such as 50%), then a scenario expressed as 25% would represent incentives being cut in half and 75% would represent incentives increasing 1.5 times. However, if the base incentives include actual incentive levels, then the base case could represent a mix of incentives that are above or below 50% of incremental technology cost. In this situation, the base percentage (such as 50%) would only be applied to measures where either the incentive is unknown or the measure is not yet part of the utility portfolio. For those measures with incentives set at the base case percentage (such as 50%), then a scenario expressed as 25% would represent incentives being cut in half, and 75% would represent incentives increasing 1.5 times. For those measures using actual incentive levels, the scenario expressed as 25% would also represent incentives being cut in half, and 75% would represent incentives increasing 1.5 times. If the current base incentive of 50% represented 25% of incremental cost, the 75% incentive scenario would represent an incentive of 37.5% of incremental cost. Additionally, incentives are capped at 100% of incremental cost. The exception is if the base incentive is already above 100% of incremental cost; in this instance, the incentive does not change.

The year in which the higher or lower incentive level goes into effect is a variable. For instance, if a utility has a mandated goal to achieve about 1.5% of sales of incremental energy efficiency each year, it may be necessary to increase the incentive in some future year in the forecast when the forecast of market potential begins to fall below the 1.5% of sales goal.

3.6.1 Scenario Adjustments to Consumer Awareness and Willingness The estimates of future decision maker measure awareness and willingness to install the measure are also affected by changes in the incentive and administrative cost levels. Increased incentive and administrative cost levels correspond to increased awareness and willingness, while decreased incentive and administrative cost levels translate to lower awareness and willingness. Changes to administrative cost is used as a proxy to simulate changes in promotional/education efforts. Modifications to these two costs can be considered independently The calculations in ELRAM assume that consumer awareness of energy efficiency measures and willingness to install the measures improves over time as long as an incentive is being offered. If no incentive or only a very small incentive is offered, consumer awareness and willingness grows very slowly and reaches a lower maximum awareness and willingness rate compared to the base case. Conversely, higher incentives generally reflect greater marketing of the utility program, which increases consumer awareness and willingness. As the scenario incentive approaches 100%, both the rate of growth in consumer willingness and awareness grow, as do the maximum awareness and willingness values as compared to the base case.
